Practical exercises at the IAEA School of Radiation Emergency Management
featuring emergency response techniques conducted in collaboration with the Policia Federal Argentina
emphasized the IAEA's steadfast support for enhancing EPR capabilities across Latin America and the Caribbean
”The school constitutes the most comprehensive training in nuclear EPR,” he said
“It offers a novel training concept by providing an integrated overview of the requirements to evaluate and improve preparedness systems for radiological emergencies.”
“Participants benefit from the expertise of first-rate IAEA specialists with extensive practical experience in emergency preparedness and response
coming from diverse organizations such as regulatory bodies
technical support organizations and nuclear operators,” said Torres Vidal
hosted by Argentina’s Nuclear Regulatory Authority (ARN) in Buenos Aires
featured a modular structure that combined theoretical and practical components
Participants attended lectures on key EPR topics
drills and tabletop exercises that simulated real-world scenarios
enabling participants to apply their knowledge in a controlled setting and encouraging future collaboration
Site visits to the National Atomic Energy Commission and the Atucha Nuclear Power Plant provided opportunities to observe emergency arrangements and response practices firsthand
Participants of the IAEA School of Radiation Emergency Management alongside the Policia Federal Argentina team
the School of Radiation Emergency Management has been
a cornerstone of the IAEA’s efforts to enhance preparedness for emergencies,” said Rodrigo Salinas
Senior Specialist on Emergency Preparedness and Response at the United Arab Emirates’ Federal Authority for Nuclear Regulation and a lecturer at the school
a response exercise at the Argentine Federal Police showcased coordinated efforts in emergency scenarios
A highlight of the course was the introduction of the importance of EPR for advanced technologies and methodologies
Participants engaged in a regional discussion on radiological monitoring networks
such as the IAEA’s International Radiation Monitoring System (IRMIS)
which supports countries in enhancing emergency response
Nuclear and radiological emergencies do not recognize national borders — as a result
international coordination and information-sharing are vital to both national preparedness and response arrangements
Underscoring the role of regional collaboration
the school’s curriculum included a role-play exercise facilitated by the National Nuclear Security Administration of the United States of America simulating the recovery of a missing radiological source and demonstrating cross-agency coordination
Chilean and Argentine experts organized a virtual simulation of radiological monitoring
and an IAEA expert demonstrated the use of unmanned aerial vehicles to perform real-time monitoring and spectra analysis
“Radiological emergency response requires specialists and appropriate technology
we included the use of drones for radiological monitoring and conducted radiological monitoring and spectra analysis in real-time
applying specific software,” said ARN expert Walter Truppa
“This exercise between Argentina and Chile serves as a clear example of regional cooperation in emergency response.”
By equipping a new generation of EPR managers with knowledge and tools based on IAEA safety standards
the programme contributes to building resilient systems that protect people and the environment from the harmful effects of ionizing radiation
not only testifies to the value of training
but to the importance of facilitating the exchange of experiences and to networking among the emergency preparedness community in the region,” said Luis Carlos Longoria Gándara
Director of the IAEA Technical Cooperation Division for Latin America and the Caribbean
“The knowledge we gained came from IAEA experts’ presentations, which reflected their vast experience in applying General Safety Requirements Part 7
along with site visits to nuclear and radioactive facilities
tabletop exercises and demonstrations of ionizing radiation detection equipment conducted during the School,” said Otilia Alcántara Bernal
a technical consultant at Mexico’s National Nuclear Safety and Safeguards Commission

Deputy Attorney General and Minister of Justice
has accused the Ghana Bar Association of attempting to circumvent the constitution
The Ghana Bar Association at its 2025 Mid-Year conference in Accra issued a communiqué and demanded that President John Dramani Mahama revoke the suspension of the Chief Justice due to its unconstitutionality
the PRO of the association in a further interview in Eyewitness News on April 29 stated that their demand is to ensure that the exercising of discretionary powers in such cases is not abused
“There ought to have been regulations in the nature of a constitutional instrument or executive instrument before exercising such discretion because the essence is to govern how it is exercised so that it doesn’t get abused
we are saying that in the absence of such regulation
we are of the view that the president has not done well,” he stated
Justice Srem-Sai stated that calls by the GBA are untenable
“If a group of lawyers meet at an event and decide that the best call they can make is that the president unmakes that which the constitution says should be private
It tells you that it is a group who are trying to subvert the constitution
“Do they need to go to law school to understand that when the constitution says something should be private
and a series of court decisions confirm that the process
and everything about it should be private?” he questioned
the Director of Legal Affairs for the National Democratic Congress
insists that the President acted within the law and did not err in suspending the Chief Justice
“A prima facie determination is derived from the validity of the petition
the terms of the constitution prevail on the chief justice
There is nothing in the constitution that prevents the Council of State from performing that constitutionally imposed duty once the president has referred the petition to them
Any attempt to stop that process will be subverting the constitution,” he said
Reverse suspension of Chief Justice immediately – GBA to Mahama

This article is part of the Research TopicLithospheric Diversity: New Perspective on Structure, Composition and EvolutionView all 14 articles
The South China Block is located on the eastern margin of the Eurasian Plate and the western margin of the Pacific Plate
The South China Block is currently in a tectonically compressed environment
while the Tibetan Plateau is moving eastward and the Philippine Sea Plate is moving westward from geodetic observations
The South China Block is an ideal place to revisit tectonic history from the Archean to Cenozoic
where its information could be well preserved in the crust
we aim to build the crustal and uppermost mantle component of the Seismological Reference Earth Model in South China (SREM-SC) to provide a background velocity model for geological interpretations and fine-scale velocity inversion
The S-wave velocity model comes from combining models inverted by ambient noise tomography and surface wave tomography
The P-wave velocity model is obtained from converted S-wave velocity and joint inversion tomography
The density model is inferred from an empirical relationship with P-wave velocity
The Moho depth is obtained by a weighted averaging scheme of previously published receiver function results
The P-wave and S-wave velocity models have a grid interval of 0.5° in both latitude and longitude
and with a vertical sampling interval of 5 km down to the 60 km depth
This work provides the 3-D crust and uppermost mantle structures and a representative reference model beneath South China
FIGURE 1. Tectonic background of South China Block. Thick red and blue lines indicate the boundaries of the major tectonic units and basins, after Zhang et al. (2003) and Su et al. (2018). Dash black lines indicate the major faults in the Chinese mainland (Deng et al., 2003)

Kennett et al. (2013) and Salmon et al. (2013) proposed an Australian Seismological Reference Model (AuSREM) using a large amount of seismological information in the Australian region
This 3D seismological reference model not only shows the main structural features of the area but also provides a detailed basic reference model for the future study of the area
The AuSREM plays an important role in Australian research and has been cited more than 100 times so far
Some velocity models in South China have been obtained by different research methods
but there may be significant inconsistencies between various models
We propose a basic reference model for South China like the AuSREM
It is very helpful to solve the above-mentioned controversial issues
The purpose of establishing the crustal and uppermost mantle component of the SREM-SC is to summarize the extensive seismological information and methods in South China over the past decades and to provide 3D seismological reference models in South China and its surrounding areas
The crustal and uppermost mantle component of the SREM-SC is grid-based
with 0.5-degree latitude and longitude sampling
The model grid ranges from 100°E to 121°E in longitude and from 18°N to 35°N in latitude
The properties of each grid point are defined by the sedimentary thickness of the basin
we created a database of well-constrained results
The Vs mainly comes from surface wave tomography
The Vp comes from converted Vs and body wave tomography
The density is obtained from the empirical relationship between the Vp and density
The crustal structure has an important influence on the tomography of the lithospheric mantle and asthenosphere, so the establishment of this model is of great value to improve knowledge of the crustal structure and the seismic tomography work (Salmon et al., 2013)
The crustal and uppermost mantle component of SREM-SC provides a reference model for other studies in this area
We gathered various types of data and then combined them to construct the 3D seismological reference model for crustal and uppermost mantle structures in South China
The data resources for constructing the velocity model mainly come from various joint tomographic inversion results
while the data resources for constructing the Moho depth map are mainly from the receiver function studies
Nine seismic models were used in this study
(A) Data resources of tomography inversion for the S-wave velocity model used in this study
(B) Data resources of receiver function for crustal thickness model used in this study
Based on the model of CRUST1.0 and the study of Xiao et al. (2021), we establish a sedimentary thickness model in South China. We provide a comparison of the different weighting values for the sediment thickness model in the supplementary material (Supplementary Figure S6), evidencing that the weighting values have little effect on the final model. CRUST1.0 is a global model with less data coverage over South China than Xiao et al. (2021)
so we think the weighting value 6:4 is an appropriate choice
The final weighting model for the sediment thickness HRef at any grid point is
where HX comes from the study of Xiao et al. (2021), HC is the CRUST1.0 model (Laske et al., 2013)
There are few studies on the sediments’ seismic velocity distributions presently and so we hope that the sediments thickness of the crustal and uppermost mantle component of the SREM-SC can stimulate the development of more detailed representations of the sediments
FIGURE 2. The thickness of sediments in the South China Block is based on the study of Laske et al. (2013) and Xiao et al. (2021)
The Moho depth of these studies showed great consistency
which may be caused by the different data sets or the details of the method (filters
FIGURE 3. Distribution of stations and the Moho depth maps from different studies. (A,B) The He et al. (2014) model, (C,D) the Li et al. (2014) model, (E,F) the Wei et al. (2016) model, (G,H) the Guo et al. (2019) model
We do not consider the estimates of the crustal thickness with a standard deviation/difference greater than 6 km in the final model
Uncertainties of crustal thicknesses determined from receiver function analysis
(A) Differences in crustal thickness for stations with two different estimates
(B) Standard deviations of crustal thickness for stations with three or more different estimates
(C) Distribution of estimates for those stations with large differences
Information about stations with standard deviation/difference estimates greater than 6 km
We have collected more than 800 estimates of crustal thickness from receiver function studies (Figure 5A) in South China after removing poor thickness estimations and redundant data. With denser station distribution, we propose a crustal thickness map in South China. The large-scale features of the result (Figures 5B,C) are similar to those of previous results (Li et al., 2014; Wei et al., 2016)
we integrate the results of all models so that it can represent the general features of the region
The crustal thickness shows a large variation from east to west
The crustal thickness along the coastal region of the Cathaysia Block is about 25–35 km
The Songpan-Gantze block has a crustal thickness of up to 60 km
FIGURE 5. (A)Distribution of receiver function data used in this study. Blue circles: Multiple measurements of crustal thickness; red triangles: one measurement from Li et al. (2014); green triangles: one measurement from Wei et al. (2016); yellow triangles: one measurement from He et al. (2014); black triangles: one measurement from Guo et al. (2019)
(B) Scatters of crustal thicknesses; (C) Interpolated results to crustal thicknesses
With the development of China’s earthquake observation system
South China has good data coverage and these studies used the three-component seismogram records from permanent and temporary stations of the China National Seismic Network deployed in South China
The crustal and uppermost mantle component of the SREM-SC is controlled by the S-wave velocity (Vs)
S-wave velocity is then used to construct the P-wave velocity (Vp) and density (ρ) fields
The velocity anomalies of these models in most areas are consistent
The Sichuan Basin shows low-velocity anomalies in the shallow crust due to the thick sediments
the low-velocity anomalies are mainly distributed in the Songpan-Gantze Block and the southeastern Tibetan Plateau
And the coast of the Cathaysia Block shows high velocities
The general consistency between the various models from different methods means that the key features of the structure are comparable
which provides a basis for constructing the crustal and uppermost mantle component of SREM-SC
we must recognize that there are some discrepancies between the models due to the different techniques and data sets
such as the distribution of the low-velocity anomalies in the Sichuan Basin at 5 and 10 km
the value of the velocity anomalies in the Songpan-Gantze Block and the Cathaysia Block at 20–60 km depth
FIGURE 6. Five published S-wave velocity models at a depth of 30 km with the same color bar from (A) Zhou et al. (2012), (B) Bao et al. (2015), (C) Shen et al. (2016), (D) Han et al. (2021), (E) Gao et al. (2022)
The velocity structure on Taiwan island is not reliable due to lacking data in (A)
To evaluate the results of our average model
we also calculated the difference between each model and the average model at each grid point
FIGURE 7. Comparison of the estimated values obtained from the conversion of Vs using the two different approaches. (A) 2D Vp/Vs ratio obtained by receiver function study (He et al., 2014) and (B) the resulting 2D converted Vp. (C) 3D Vp/Vs ratio obtained by tomographic study (Han et al., 2021) and (D) the resulting 3D converted Vp
we construct a smooth estimate of the Vp model
which provides a good representation of the velocity structure of the study region
Velocity and density are two kinds of parameters with good correlation to rock’s physical properties. Feng et al. (1986) proposed a linear relationship between velocity and density suitable for local conditions by referring to the Nafe-Drake empirical relationship and combining it with plenty of seismic data in North China when inversing the 3D potential field of gravity and magnetic. We use the empirical relationship proposed by Feng et al. (1986):
5.2 Velocity structure5.2.1 Horizontal slices
P-wave velocity distribution for the crustal and uppermost mantle component of SREM-SC at depths of (A) 5 km
S-wave velocity distribution for the crustal and uppermost mantle component of SREM-SC at depths of (G) 5 km
regions with a thicker crust usually have lower velocity values than regions with a thinner crust
The P-wave velocity and S-wave velocity in the crustal and uppermost mantle components of the SREM-SC at 40 and 60 km depth are shown in Figures 9E,F,K,L
the velocity characteristics remain in the same distribution pattern as at 30 km depth
the whole study area displayed as high velocities
while the southeastern Tibetan Plateau retains some low-velocity characteristics
Figure 10 shows five representative vertical cross sections through the crustal and uppermost mantle component of the SREM-SC. The sections at latitude 25°N, latitude 30°N, longitude 110°E, longitude 115°E, and an oblique section extending from the southeast to northwest of the study region are presented in depth slices of S-wave velocity at 30 km depth (Figure 10F)
Vertical S-wave velocity sections of the crustal and uppermost mantle component of SREM-SC along profiles (A) latitude at 25°N
(D) longitude at 110°E; (E) longitude at 115°E
The profile locations are shown in the map view (F) at 30 km
Moho depth of this study (solid black line) is also shown in the map
By comparing our new Moho depth (Figure 5C) discussed in section 4 with the vertical sections of the S-wave velocity
we found a good correspondence between the Moho depth and the Vs of 4.0 km/s
We can see from these sections that the Moho depth increases from southeast to northwest and crustal thickness is positively correlated with topography
FIGURE 11. Velocity difference of the averaged S-wave velocity model at 30 km depth relative to the models of (A) Zhou et al. (2012), (B) Bao et al. (2015), (C) Shen et al. (2016), (D) Han et al. (2021), (E) Gao et al. (2022)
FIGURE 12. Percentage histograms of velocity difference distribution from the average model, calculated at each node, at 30 km depth for (A) Zhou et al. (2012), (B) Bao et al. (2015), (C) Shen et al. (2016), (D) Han et al. (2021), (E) Gao et al. (2022)
The dashed gray lines indicate the velocity difference of 0%
The velocity obtained by surface wave inversion is generally lower than the average model
while that obtained by joint inversion is generally higher than the average model
Reasons for these differences may include different types of original data
We do not determine which model is better or worse
we just attempt to analyze the differences and similarities between the previous models and the newly established average model
We propose the crustal and uppermost mantle component of the Seismological Reference Earth Model in South China (SREM-SC) from many published seismic models
which can serve as a new reference model for the velocity structure of the South China lithosphere
The crustal and uppermost mantle component of SREM-SC is grid-based with a 0.5° sampling in both latitude and longitude
and with vertical sampling points at 5 km intervals to the depth of 60 km
Each grid point is defined by the thickness of the sediments
The S-wave velocity comes from the ambient noise and earthquake surface wave tomography and the information for the P-wave velocity is a combination of estimates by conversion of Vs using the Vp/Vs ratio and the joint inversion
The density is inferred from empirical relationships between P-wave velocity and density
The Moho depth is obtained by weighted averaging of previously published receiver function results
The crustal and uppermost mantle component of SREM-SC describes the major lithosphere features in South China
we must recognize the limitations of this model
There is no dense P-wave velocity information in the crust of South China
and we limit it by conversing from S-wave velocity
The model can be improved by adding more information constraints
The crustal structure has a significant impact on the tomography of the lithospheric mantle and asthenosphere
The establishment of the crustal and uppermost mantle component of SREM-SC is critical for understanding the crustal structure and improving seismic tomography work
And it can also be used as the initial model for seismic wave propagation simulation
crustal correction for tomography inversion

Deputy Attorney-General Justice Srem-Sai has disagreed with the call by the Ghana Bar Association (GBA) on the President to rescind the suspension of the Chief Justice
The GBA had declared the suspension of Chief Justice Gertrude Torkornoo as unconstitutional
This was a key point in a statement released at the GBA’s 2025 Mid-Year Conference in Accra
They argued that the way the Chief Justice was suspended goes against Ghana’s laws
They believe that President John Dramani Mahama did not follow the correct legal procedures
the GBA states that the President did not publish an official document (Constitutional Instrument
or Regulation) to explain how he came to his decision
The Association points out that a previous legal case
dealt with the importance of publishing such documents
The GBA is therefore calling for the suspension to be reversed immediately
In addition to the issue of the suspension
These rules would cover how to handle situations involving judges of the Superior Courts
especially in cases that could lead to their removal from office
The GBA believes this will make the process more transparent
Justice Srem-Sai said “If a group of lawyers meet at an event and decide that the best call they can make is that the president unmakes that which the constitution says should be private
“Do they need to go to law school to understand that when the constitution says something should be private
and a series of court decisions confirm that the process
and everything about it should be private?” he questioned

Deputy Attorney General-designate
The Minority in Parliament has rejected the nomination of Justice Srem-Sai as Deputy Attorney General and Justice Minister-designate after a disagreement with the Chairman of the Appointments Committee
The dispute happened during the vetting process when Minority Leader
asked Srem-Sai to demonstrate a traditional dance
He described the Chairman’s decision as “whimsical” and said he was “rudely interrupted,” calling it unfair treatment toward the Minority
the Minority announced their rejection of Srem-Sai’s nomination
Afenyo-Markin further stated that since the vetting began on Monday
they have also rejected the nominations of three other deputy minister-designates: Alhassan Suhuyini (Roads and Highways)
Sulemana Yussif (Lands and Natural Resources)
He accused the Majority side of repeatedly interrupting his questioning of Srem-Sai
“The Minority caucus rejects the nomination of the Deputy Attorney General
Any decision on this will be solely yours as the Majority caucus
we are also rejecting all other nominees today,” Afenyo-Markin said

A member of the National Democratic Congress (NDC) legal team, Justice Srem Sai, has raised concerns over the legitimacy of three New Patriotic Party (NPP) candidates declared as Members of Parliament-elect.
“And so, this morning, we are filing a certiorari to quash the swearing-in. In the light of all these, I do not honestly see how anybody will bless these three alleged MPs with any swearing-in this evening or tomorrow”, he stated.
However, Justice Srem Sai has described the process as unconstitutional and announced plans to appeal to the Supreme Court. The NDC also intends to file a certiorari to prevent the swearing-in of the disputed MPs-elect.
Moreover, the candidates, Patrick Yaw Boamah, Charles Forson, and Martin Adjei-Mensah Korsah, were declared winners of their respective parliamentary seats in Okaikwei Central, Tema Central, and Techiman South constituencies after a court-ordered collation of results.
Speaking on the Citi Breakfast Show on Monday, January 6, Justice Srem Sai compared the current dispute to the case involving John-Peter Amewu during the 2020 Hohoe parliamentary election

This work is the mantle component of constructing the Seismological Reference Earth Model in South China (SREM-SC)
Although there has been a wide range of research for imaging the upper mantle structures beneath South China
most of them focus on the large-scale features of the upper mantle
and the depth resolution is insufficient for existing surface wave tomography models to distinguish anomalies below 200 km
This study aims to develop a 3-D upper mantle Seismological Reference Earth Model in South China based on the prior tomography models
The shear wave velocity model comes from the analysis of several seismic surface wave tomography
supplemented by body wave tomography and the P-wave velocity model is constructed by the conversion from S-wave velocity
The radial anisotropy model is calculated from the SV-wave and SH-wave velocity
The Density model of the upper mantle is derived using the empirical relationship linking the density to the shear-wave velocity
The model is grid with 0.5° × 0.5° in latitude and longitude and 5 km interval in depth from 60 to 300 km
The mantle component of Seismological Reference Earth Model in South China is expected to provide a good representation of the upper mantle structures for further detailed studies
The mantle component of Seismological Reference Earth Model in South China provides new insights into upper mantle structures that should be meaningful to reveal the dynamic mechanism and tectonic evolution of South China
which were affected by the westward subduction of the Pacific plate
compression and relative plate motions of the major tectonic domains (the westward subduction of the Pacific plate
the formation of the Tibet Plateau and northward differential movement of the India Australia plate) in the Mesozoic and Cenozoic led to a complex tectonic environment of the SCB
thus it’s necessary to establish a reliable and robust velocity model in order to learn more about the tectonic evolution of SCB
To better study the lithospheric structure
we conduct a joint inversion of body- and surface-wave data to determine a high-resolution Vs model of South China
This study aims to build a reliable 3-D mantle component of Seismological Reference Earth Model in South China (SREM-SC) down to a depth of 300 km based on these different styles of prior tomographic models
which will capture the major features of the upper mantle in South China and serve as an initial model for further study of more detailed velocity structures or prediction of seismic wave fields
and provides new insights into the dynamic process of the lithospheric evolution of the South China
The China National Seismic Network Center and domestic research teams (e.g., Zheng et al., 2010) have set up a large number of broadband permanent and portable stations in South China and its surroundings (Figure 2A), providing excellent data resources as the foundation for studying the lithospheric structure. With the numerous earthquakes that occur along the circum-Pacific belt and on the Tibetan Plateau (Figure 2B)
these rather dense stations in South China offer a good ray coverage
allowing for the achievement of a decent resolution
(A) Distribution of permanent and portable seismic stations (blue triangles) in the South China Block (B) Insert map: Configuration of seismic stations and seismic events with Ms > 5.5 for the year 2016
to illustrate the potential ray path coverage
the joint inversion of ambient noise and earthquake surface wave tomography can be helpful to improve the structures in the upper mantle
Previous tomographic models used in this study
Figure 3 and Figure 4 illustrate the selected models with absolute velocities at depths of 70 km and 140 km
Only one-half of the models show a velocity structure below 150 km
The velocity anomalies of these models in the Yangtze Craton and Cathaysia Block are basically consistent
the western Yangtze Craton shows fast velocity while the Cathaysia Block
and North China Craton exhibit slow velocity
the western Yangtze Craton exhibits high-velocity anomaly and the Cathaysia Block primarily shows low-velocity anomaly despite the diversity of anomalous characteristic
The general consistency between the various models from surface waves and body waves means that the key features of the structure are comparable and well defined
which provides a basis for constructing the mantle component of SREM-SC
we have to recognize that there are some discrepancies between the basic models due to the different techniques and data sets
FIGURE 3. Shear wave velocity for the six SV wave models at 100 km depth from (A) Zhou et al. (2012) (B) Bao et al. (2015) (C) Shen et al. (2016) (D) Tang et al. (2022) (E) Han et al. (2021) (F) Gao et al. (2022)
FIGURE 4. Shear wave velocity for the three SV wave models at 200 km depth from (A) Zhou et al. (2012) (B) Shen et al. (2016), and (C) Tang et al. (2022)
We establish the representative mantle component of Seismological Reference Earth Model in South China (SREM-SC) on the basis of information available in the earlier studies, by imitating the construction process of the Australian Seismological Reference Model (AuSREM, Salmon et al., 2013; Kennett et al., 2013)
The major control on the mantle component of SREM-SC comes from the shear wave velocity distribution derived from tomographic results
P-wave velocity and density are then conducted from shear wave velocity
The mantle component of SREM-SC is specified in terms of absolute velocities and the primary model nodes are spaced at 0.5° apart in latitude and longitude and 5 km apart in depth from 60 km to 300 km
The main contribution to the SV distribution is constructed from the available tomography models mentioned in the last section
Considering the vary grid sizes and depth intervals of these chosen models
we re-interpolate these models to ensure that they share the same range and interval of longitude
In constructing the mantle component of SREM-SC
we seek to provide a representation where the major features are robust and reliable
we adopt the linear combinations of these shear-wave velocity models with equal weight to emphasize such features
average these models to obtain the final averaged SV wave model
The tendency is for smaller scale features to be obscured
We give the model same weight because the used seismic stations were similar
which also means that the ray path coverage was comparable
SV wave velocity of the mantle component of SREM-SC at depths of (A) 60 km (B) 140 km (C) 220 km
other models show slow velocity than the average model
FIGURE 6. Horizontal slices at 100 km depth through SV wave velocity showing the relative velocity difference between regional models of (A) Zhou et al. (2012) (B) Bao et al. (2015) (C) Shen et al. (2016) (D) Tang et al. (2022) (E) Han et al. (2021) (F) Gao et al. (2022) and the mantle component of SREM-SC
might be attributed to the deep source mantle plume in this area
FIGURE 7. SH wave velocity of the mantle component of SREM-SC at (A) 60 km (B) 140 km (C) 220 km, and (D) 300 km depths using the result of Tang et al. (2022)
however the majority of them focus on the shallow crust and lack depth constraints on the upper mantle
we construct a representative radial anisotropy model in the upper mantle of SCB by combining the previously stated SV wave and SH wave models
The definition of radial anisotropy is ξ=VSH2/VSV2
positive radial anisotropy with ξ > 1.0 (VSH > VSV) indicates the effects of horizontal shear flow or a horizontally layered structure
whereas negative radial anisotropy with ξ < 1.0 (VSH < VSV) is interpreted as the influence of vertically oriented structures or mineral alignment
which suggests the upwelling of mantle materials penetrating the MTZ to thicken the local crust
FIGURE 8. Radial anisotropy distribution of the mantle component of SREM-SC at (A) 60 km (B) 140 km (C) 220 km, and (D) 300 km depths, determined from the SV wave velocity of SREM-SC and SH wave velocity of Tang et al. (2022)
FIGURE 9. The construction process of P wave velocity of the mantle component of SREM-SC keyed at a map view of 100 km depth (C) The converted P wave model is obtained by combing (A) the averaged SV wave model with (B) the Vp/Vs ratio from the FWEA18 model (Tao et al., 2018), and then averaged with (D) the P wave velocity from USTClitho2.0 model (Han et al., 2021) to build (E) the final P wave velocity of the mantle component of SREM-SC
caused by the dehydration of the Paleo Pacific subduction plate detained in the mantle transition zone in the Mesozoic
The high P wave velocity beneath Yangtze Craton is usually associated with low Vp/Vs ratio
thick lithospheric root and lower temperature
P wave velocity of the mantle component of SREM-SC at depths of (A) 60 km (B) 140 km (C) 220 km
but there is less direct information on the density of the upper mantle
a density scales to a velocity perturbation or absolute velocity are given as follows:
The eastern Tibetan Plateau is characterized by low density
the density characteristics of the eastern and western SCB are obviously different
that is the Cathaysia Block shows low density while the Yangtze Craton exhibits high density
the density anomaly of Yangtze Craton is slightly larger than that of the Cathaysia Block
The density distribution pattern has a good correlation with the tectonic unit
and the Cathaysia Block correspond to low density
which maybe related to the subduction of Pacific Plate
The density is constructed by quantitative estimation of SV wave velocity
which can be used as the initial of the joint inversion of P wave velocity and gravity in the future to concentrate the advantages of the two methods
FIGURE 11. The density distribution of the mantle component of SREM-SC at depths of (A) 60 km (B) 140 km (C) 220 km, and (D) 300 km, calculated from the empirical relationship proposed by Kennett et al. (2013) between the density and shear wave velocity. The solid black lines in (A) denote the location of cross-sections in Figure 12, Figure 13
We propose a 3-D representative upper mantle component of Seismological Reference Earth Model in South China (SREM-SC)
we employ the SV wave velocity as the primary control
P wave velocity and density based on the relationship between variables with SV velocity
(2009) believed that the low velocity anomaly was due to the thermochemical effect of the subduction of the Sulu Ocean crust
FIGURE 12. Vertical Cross-sections of the mantle component of SREM-SC along profiles (A) W1-E1 at 25°N and (B) W2-E2 at 30°N indicated in Figure 11A
Topography is plotted above each cross-section
and the red lines are the approximate border of the main tectonic units
FIGURE 13. Same as Figure 12, but along profiles (A) S1-N1 at 105°E and (B) S2-N2 at 115°E, indicated in Figure 11A
the density differences are modest and do not show much dependence on the high velocity zones
as the seismic S-wave result is the only factor that constrain the density structure
it is preferable to combine the gravity and seismology inversions in order to reduce the non-uniqueness of inversion and improve the horizontal and vertical resolution
we realize that the reference model will be further improved based on new information in the future to better construct the lithosphere and asthenosphere boundaries

Deputy Attorney-General and Minister of Justice nominee
Justice Edem Srem-Sai took his turn at the vetting committee on Wednesday
Srem-Sai was the second nominee to face the Appointments Committee after Deputy Minister-designate for Roads and Highways
Afenyo-Markin took his turn with the nominee after Srem-Sai had spent over an hour answering questions from the various committee members
an interesting moment caught the attention of many during Afenyo-Markin’s turn with Justice Srem-Sai
The minority leader after questioning the nominee about his hometown asked him to briefly demonstrate the ‘Akpi’ dance after the nominee ascribed to the dance as part of his tribe’s culture
kindly demonstrate the Akpi dance for a bit
just for a second,” Afenyo-Markin asked the nominee
Bernard Ahiafor overruled Afenyo-Markin’s request asking Srem-Sai not to demonstrate the ‘Akpi’ dance
He said the vetting procedure is not a forum for demonstrations but an Appointments Committee mandated to vet nominees
You are not going to demonstrate,” Ahiafor stated
Afenyo-Markin accused Ahiafor of rudely interrupting the proceedings
saying Bernard Ahiafor is acting “capriciously”
“Chairman if you decide to be whimsical and capricious
it will not advance the work of this proceedings
Apart from the constitutional matters involved
We’ve had nominees who have spoken their languages,” Afenyo-Markin remarked
the Chairman took offense to the Minority Leader’s comment and demanded that he withdraw his comment and apologise
“Honourable Minority Leader I take offense to you saying I’m acting whimsical and capricious so I urge you to withdraw those words you use on me,” Bernard Ahiafor demanded
But Afenyo-Markin vehemently refused and stood by his comment
You were whimsical and capricious in the way you overruled my question
Bernard Ahiafor to end the vetting unexpectedly by ordering the Minority Leader not to proceed with asking any question further
to demonstrate to you that I am the Chairman of this particular vetting committee
that may be your last question,” Ahiafor declared
The Appointments Committee Chairman went ahead to discharge the Deputy Attorney-General and Minister of Justice nominee
Deputy Minister of Justice and Attorney General
Justice Srem Sai has said that the raid on the home of former Governor of the Bank of Ghana
Dr Ernest Addison was done in accordance with the law
He states that warrants were procured and used for the raid
“We take responsibility for the search that happened
We want to make it clear that those searches and the mode in which they were done were in accordance with the law
Warrants were procured and used,” he told journalists in Accra on Thursday
Shamima Muslim had said that there should be no problem once due process is followed in raiding the homes of officials who served in the previous administration
This was after she justified the alleged home raiding and arrest of some former officials who served under the erstwhile NPP administration
“I’m yet to get to the office to receive a full briefing on the matter but what I can say is that there are some actions going on
there are persons of interest who will be now and again invited to help the investigation process
and one of the means is to visit the homes of these persons of interest,” she explained
She further called for due process to be followed in the arrest of these individuals

Following the raiding of the former BoG’s home and the arrest of Okatakyie
Afenyo-Markin and other NPP executives condemned the act
highlighting the need for respect of democracy and human rights
Shamima Muslim argued that the Minority’s response to the action taken by government is an attempt to evade accountability by trying to sabotage the NDC government
She asserted that the NDC government is more respectful in its demand for accountability than what was witnessed under the NPP government
referencing unfair treatment experienced by some NDC officials in 2017 when former President Akufo-Addo assumed office
we should also be mindful of how the minority would always deliberately position themselves to be avers to any action that government takes in its quest to demand audit and accountability of the outgone government…sometimes exaggerating the issue and trying to deliberately misrepresent the action that is being taken
Se was reacting to the allegations that National Security Operatives on Wednesday
raided the home of former Bank of Governor
Okatakyie Afrifa Mensah was also arrested by National Security Operatives and released later in the evening
Ken Ofori-Atta was also allegedly raided by some national security operatives who in addition searched the home of the former minister

Justice Srem-Sai
Justice Srem-Sai has said that he stands by his earlier comment that he saw a memo that was written to former A-G Godfred Dame to discontinue the trial of former Deputy Governor of the Bank of Ghana (BoG)
Dr Johnson Asiama who has now been appointed Governor
Appearing before the Appointments Committee of Parliament on Wednesday
Asked whether he will be able to provide the said memo
he said “I am unable to provide evidence of the memo because of my current status…I saw it from electronic trails of the memo and I saw it in my capacity as a private citizen.”
the former A-G had challenged his successor Dr
to provide evidence of a memo recommending the withdrawal of charges against Bank of Ghana Governor
Dame had insisted that no such document existed and asserted that the decision to drop the charges by Mr Ayine was based on falsehoods
Ayine defended his decision to discontinue the prosecution against Dr
citing a case review that exposed significant weaknesses in the evidence
He claimed his reassessment uncovered an internal memo from the prosecution division of the Attorney General’s office
which advised former AG Godfred Yeboah Dame to drop the charges due to concerns over the case’s strength
Ayine emphasized the memo’s role in shaping his decision
“My review of some of the cases revealed fatal flaws in the case of the prosecution
I took the decision to withdraw the charges against Mr
Johnson Asiama for the simple reason that in the course of my review of the cases
my attention was drawn to an internal memo prepared by the prosecutions division of our department for the attention of the former AG
which recommended that the charges against him be dropped
But speaking at a press conference on Friday
I do not recall receiving any such memo from the Prosecutions Division
Ayine to produce such a memo for the examination of the public as he has touted same to the public at a press conference as the basis for his impugned actions.”
Justice Srem-Sai has told the Appointments Committee of Parliament that his Doctorate Degree Programme abroad was funded by the Ghana Education Trust Fund (GETFund)
He did his PhD at the University of Leeds School of Law
His areas of research included constitutional law enforcement
He said it cost the state around 20,000 Pounds a year for the tuition to complete the project
Asked for the sources of funding for his programme while appearing before the Appointments Committee of Parliament on Wednesday
he said “My PhD abroad was funded by GetFund.”
“GETFund has on record all the people and how much they have paid
I will recommend that GETFund can provide,” he said when asked whether he would be able to provide evidence of the cost
Dr Johnson Asiama who has now been appointed Governor
I do not recall receiving any such memo from the Prosecutions Division
Ayine to produce such a memo for the examination of the public as he has touted same to the public at a press conference as the basis for his impugned actions.”

The Minority in Parliament has rejected the nomination of Deputy Attorney General and Justice Minister-designate
following a disagreement with the Chairman of the Appointments Committee
The dispute arose when Minority Leader Alexander Afenyo-Markin requested Srem-Sai to demonstrate the traditional dance a move the Chairman vehemently opposed
Afenyo-Markin described the Chairman’s stance as ‘whimsical’ and claimed he was ‘rudely interrupted,’ indicating unfair treatment toward the Minority
After a ten-minute suspension of the vetting process
the Minority returned and declared their rejection of Srem-Sai’s nomination
despite smooth vetting sessions since Monday
they have also rejected the nominations of Alhassan Suhuyini
Deputy Minister-designate for Roads and Highways who had been vetted already
Deputy Minister-designate for Lands and Natural Resources
“When it got to me the leader of the caucus
Including an interruption by the Attorney General [Dr Dominic Ayine] himself
of which you curiously said you never heard
It was aimed at obstructing the smooth process of my vetting of the nominee [Srem-Sai]
you allowed him to ask a so-called follow-up question
“The minority caucus rejects the nomination of the Deputy Attorney General and that the decision of it will be solely yours as majority caucus
all other nominees in furtherance of our protest
we’re also rejecting them and your decision will remain yours as majority caucus.”

Deputy Minister-Designate for Attorney-General and Justice
Justice Srem-Sai has disclosed that his doctoral studies at the University of Leeds School of Law in England were financed by the Ghana Education Trust Fund (GETFund)
He mentioned that the state incurred approximately £20,000 annually for his tuition
This revelation came during his appearance before Parliament’s Appointments Committee on Wednesday
“My PhD abroad was funded by GetFund
GETFund has on record all the people and how much they have paid
I will recommend that GETFund can provide.”
This revelation comes in the context of previous reports highlighting that several lecturers
benefited from GETFund scholarships intended to support higher education pursuits
The vetting of Deputy Attorney General and Justice Minister-designate
took an unexpected turn following a heated exchange between the Chairman of the Appointments Committee and Ranking Member
Tensions flared after Afenyo-Markin requested the nominee to demonstrate a particular dance
the Chairman found the request inappropriate for the setting and overruled the question
Afenyo-Markin accused the Chairman of being “whimsical and capricious” in his handling of proceedings
The Chairman then demanded that Afenyo-Markin withdraw his remarks
Chairman Bernard Ahiafor firmly asserted his authority
“To demonstrate to you that I am the chairman of this particular vetting committee
The escalating dispute ultimately led to an abrupt end of the vetting session
The Minority members of Parliament’s Appointments Committee have rejected the nomination of the Deputy Minister for Justice and Attorney-General
Three other Deputy Ministerial nominees who appeared before the Committee today
February 26 were also rejected by the Minority
The decision was announced by the Minority Leader
“I wish to announce a decision we have taken as Minority Caucus of the Appointment Committee
We have taken note of the abrupt end of the vetting of the nominee for Deputy Minister of Justice and Attorney-General
We reject the nomination of the Deputy Minister of Justice and Attorney-General,” Mr Afenyo-Markin said
“Any decision to approve the nominee shall be the sole responsibility of the Majority,” he added
we are also rejecting all other nominees vetted today
and any decision taken will remain yours,” Afenyo-Markin declared
The Minority Leader made the announcement upon resumption of proceedings of the committee after it ended suddenly when Mr Srem-Sai was being vetted
Mr Afenyo-Markin had asked the nominee to demonstrate how a dance in the Volta Region (Akpi dance) is performed
This request was overruled by the Chairman of the Committee
Mr Afenyo-Markin described Mr Ahiafor’s action as “whimsical and capricious”
This remark did not go down well with Mr Ahiafor
thus he asked the latter to withdraw or cease asking further questions
which compelled the Chairman to end proceedings
In response to the Minority Leader’s statement to the effect that they have rejected the nominee
“I take exception to being described as whimsical
When you want to turn the vetting room into a dancing floor
“You are even lucky that I have not cited you for contempt.”
Srem-Sai’s vetting ends abruptly over Afenyo-Markin’s refusal to withdraw ‘capricious’ comment against Ahiafor
The minority are there to do nothing but rather to delay the development and the growth of the economy
has defended the recent raid on the home of former Bank of Ghana Governor
His remarks follow allegations against National Security operatives for raiding Dr
journalist Okatakyie Afrifa Mensah was reportedly arrested and later released
security personnel allegedly searched the residence of former Finance Minister Ken Ofori-Atta
The Minority has strongly condemned these incidents
Speaking to journalists in Accra on Thursday
Srem-Sai took responsibility for the raid and clarified that it was carried out with proper legal authorization
Warrants were procured and used,” he stated
His comments come amid growing concerns over the conduct of security operations targeting former government officials

Deputy Attorney General and Minister of Justice
has underscored that the current tension between the executive and the legislature does not portend a loss for the country
Srem Sai’s comments follow concerns that the Speaker of Parliament’s decision to halt the approval process of ministers designate could have an economic impact on the country in terms of governance
I think there is no loss with what is happening,” he stated on TV3’s political analysis programme The Key Points on Saturday
The constitutional lawyer was of the view that the court cases would rather help the country in the long term as the court will
determine if a person performing a constitutional mandate can be prevented by a court writ from doing so
we may think that this is costing us but in the long term
certain things will not repeat themselves,” he added
“We can still discuss this state of confusion without bringing up the LGBT issue because whatever decision they’re taking now
whatever the court will rule now in the future will have nothing to do with LGBT,” he said
He continued that the outcome of the case “would have everything to do with how the President is supposed to behave when there is a law being passed in parliament
whether someone can interfere or interrupt the process of lawmaking.”
emphasising that the size of the government is already overbloated
He therefore urged President Akufo-Addo to take a cue from Vice President Dr
who has said that he will run a lean government with a maximum of 60 ministers when elected president
that the House is unable to continue the processes that would lead to the approval of ministers designate vetted by the Appointments Committee
In a 62-point letter in response to President Akufo-Addo’s letter on the anti-LGBTQ bill to Parliament noted that the decision has been occasioned by the pendency of an interlocutory injunction filed by the Member of Parliament for South Dayi
the receipt of a process from the Courts titled Rockson-Nelson Etse K
Dafeamekpor vrs the Speaker of Parliament and the Attorney-General (Suit no
J1/12/2024) which process was served on the 19th of March 2024 and an injunction motion on notice seeking to restrain the Speaker from proceeding with the vetting and approval of the names of the persons submitted by His Excellency the President until the provisions of the constitution are satisfied
the House is unable to continue to consider the nominations of His Excellency the President in the “spirit of upholding the rule of law“ until after the determination of the application for interlocutory injunction by the Supreme Court,” said Speaker Bagbin
Justice Srem-Sai has said that the A-G Dr Dominic Ayine will gather evidence before prosecuting any case
He told the Appointments Committee of Parliament during vetting that evidence gathering will be done before persons are sent to court
“My boss will not prosecute before the court before looking for evidence,” he said
“I will assist my boss on the use of IT to fast-track cases.”
Srem-Sai told the committee that he stands by his earlier comment that he saw a memo that was written to former A-G Godfred Dame to discontinue the trial of former Deputy Governor of the Bank of Ghana (BoG)
Ayine to produce such a memo for the examination of the public as he has touted same to the public at a press conference as the basis for his impugned actions.”

Member of Parliament for Suame
Deputy Attorney General Dr Justice Srem-Sai has criticised the abuse of parliamentary immunity
warning that measures will be taken to correct and prevent its misuse
Dr Srem-Sai addressed concerns over the misuse of MPs’ constitutional protection against defamation lawsuits
emphasising that this privilege exists to enhance good-faith parliamentary debate rather than serve as a shield for false or malicious commentary
“The Constitution grants MPs some protection against defamation suits
the purpose of this protection is to enhance the quality of GOOD FAITH parliamentary debate
The protection is not a security for false or malicious commentary,” he wrote
an unnamed MP had exploited this protection by making false and damaging statements in Parliament
creating public disaffection toward individuals
an MP has chosen to abuse this protection by using the premises of Parliament to peddle malicious falsehoods
which has resulted in creating public disaffection and opprobrium for persons
defeats the purpose of the constitutional protection,” he added
Dr Srem-Sai also refuted claims that former Bank of Ghana Governor
was mistreated during a National Security search of his residence
He asserted that Dr Addison had legal representation throughout the process and that the search was conducted cordially and within court-authorised terms
“Dr Addison had access to legal counsel and representation throughout the search
The search was conducted in line with the terms of the court authorisation; and cordially,” he stated
The Deputy Attorney General reaffirmed the government’s commitment to addressing the misuse of parliamentary privileges
stressing that such abuses will be corrected to ensure a healthy democratic environment
“Such abuse of MPs’ constitutional protection will be corrected and remedied for the healthy growth of our democracy,” he concluded
This statement signals a possible legal or parliamentary intervention to ensure that constitutional protections for MPs are not exploited for misinformation or personal attacks

John Darko has defended Minority Leader Alexander Afenyo-Markin over his controversial request for Deputy Attorney General and Justice Minister-designate
to demonstrate a cultural dance during his vetting before Parliament’s Appointments Committee
Afenyo-Markin’s request was an attempt to connect with the nominee on a personal level and help Ghanaians learn more about him
was unexpectedly cut short following a heated exchange between Appointments Committee Chairman Bernard Ahiafor and Afenyo-Markin
The dispute arose when Afenyo-Markin asked Justice Srem-Sai to dance
arguing that cultural appreciation was an essential aspect of the vetting process
It is also about our culture,” Afenyo-Markin stated
who accused the Chairman of being “whimsical and capricious” in his handling of proceedings
John Darko justified Afenyo-Markin’s approach
insisting that it was not a trivial request but a way to introduce the nominee to the public
“There are more things we look out for than what you see
you may not see this question as unnecessary
It will not even be the determining factor of his approval
It is just for the people of Ghana to get to know him,” he explained
He emphasized that the vetting process goes beyond legal and professional qualifications
stating that a nominee’s background and personality are also considered
“To determine the suitability of a person
you take a lot of things into consideration
There was even a question of where he came from… So
and he [Afenyo-Markin] went on culture after asking him several other questions
and that doesn’t sound like the traditional name you would expect from a person coming from the Volta Region
but the Minority Leader and Ghanaians don’t know him
he was trying to get to know him by asking him all of those questions.”
