UFM: Upper Freshwater Molasse; SSDS: soft-sediment deformation structures; Tobel is the local term for a small ravine in southern Germany) The Upper Freshwater Molasse deposits that overlie (i.e. postdate) the DREL are typically cross-bedded or horizontally layered and generally appear undisturbed and unaffected by dewatering processes Faunal assemblages (European Land Mammal Zones ELMZ) that occur within the Ries and Steinheim crater lake deposits and in context with the distal Ries ejecta horizon the ELMZ also comprise the typical floral and faunal (e.g. the slumped deposits do not occur at the basis of the lake deposits which would have been favored by the steep relief of the newly formed precipitous impact crater; but soft-sediment deformation appears to be dominant in the middle of the sedimentary succession The slumps and convolute bedding within the Ries crater lake could well represent a long-distance effect of a strong earthquake some hundred kyr after the Ries impact potentially triggered by the Steinheim impact only some 40 km SW of the Ries crater The time gap of approximately 0.5 Myr also fits the purported age difference between the crater lake deposits at both impact structures as well as the post-Ries timing of active slumping within the Ries crater lake sediments combined with the lack of an effective seismic source for a high-magnitude earthquake postdating the Ries event lead us to conclude that the Ries and Steinheim impact structures might be the result of two temporally separate impact events in southern Germany occurring ~ 40 km and ~ 0.5 Myr (and up to 1 Myr?) apart The occurrences of the seismite near Biberach and Bernhardzell are the first reported deposits in which evidence for earthquake-induced soft-sediment deformation structures caused by the Ries impact has been documented this is also the first known occurrence of a primary continental seismite-ejecta couplet exposed in situ the earthquake magnitude–distance relationship for liquefaction effects is currently still underexplored and needs to be evaluated from the perspective of geologically younger major earthquakes Hammer for scale is approximately 30 cm long Photograph taken in Kleintobel close to Ravensburg by V.J.S small airborne ejecta particles and ash from the impact plume probably reached the higher troposphere and stratosphere and caused havy rainfall for days (and possibly for weeks or months due to the atmospheric disturbance) after the impact event The intact nature of bones and teeth document that these fossils were not significantly reworked and that the finding situation is more or less in situ the same region was affected by a second set of catastrophic effects presumably induced by the Steinheim impact event that produced large dikes cutting through the Ries seismite–ejecta couplet and the overlaying layers of Upper Freshwater Molasse With the Ries and Steinheim impacts as an extraterrestrial one-two punch Southern Germany seems to have witnessed a veritable double disaster in the Middle Miocene We paid particular attention to ravines in the areas of Biberach and Ravensburg in SW Germany and Bernhardzell (St After heavy rainfall in the Biberach and Ravensburg area in spring 2019 deposits with soft-sediment deformation structures and clastic dikes were partially exposed below and above the distal ejecta horizon along the valley sides of the ravines The structures were excavated during eight field campaigns from spring to winter 2019 We excavated the sandy foreland basin deposits over a vertical extension of 15 m along the flank of the ‘Tobel Oelhalde-Nord’ (Biberach) and over tens of metres laterally along the flanks of the ravines ‘Tobel Oelhalde-Nord and –Süd’ (Biberach) and Kleintobel (Ravensburg) Thin sections of the dike's infill were analyzed for their petrographic properties using a polarization microscope Additional unconsolidated samples of the infill were investigated by reflected-light microscopy to assess their fossil content (e.g. this method requires the detailed analysis of a large number of shocked quartz grains Due to their rare nature in the distal Ries ejecta horizon this study does not provide systematic PDF statistics an equation that correlates the impact energy with the resultant seismic magnitude (ML) was derived: Modeling the Ries–Steinheim impact event and the formation of the moldavite strewn field Ries crater and suevite revisited—observations and modeling part II: modeling Ries crater and suevite revisited—observations and modelling Steinheim Suevite—a first report of melt bearing impactites from the Steinheim Basin (SW Germany) The Steinheim Basin impact crater (SW-Germany)—where are the ejecta?

NASA’s Juno Back to Normal Operations After Entering Safe Mode Metrics details the Nördlinger Ries and Steinheim Basin in southern Germany have been regarded as a textbook example of a terrestrial impact crater doublet although the oldest crater lake deposits in both craters suggest a biostratigraphic age difference of ~ 0.5 to 1 Myr We previously presented stratigraphic arguments that challenged the double impact scenario and favoured a model of two temporally independent impact events in the Mid-Miocene four localities within a distance of ~ 50–100 km from the Ries and ~ 50–70 km from the Steinheim crater that expose two independent seismite horizons together unique within the Upper Freshwater Molasse of the North Alpine Foreland Basin each one featuring impressive water escape structures The seismite horizons are separated by ~ 10 to 15 m of undisturbed Molasse deposits and thus providing evidence for two independent major seismic events within a time span of ~ 0.5–1 Myr Both the lower and the upper seismite horizons can be correlated litho- and biostratigraphically with the basal crater lake sediments at the Ries and Steinheim craters the impact event that formed the Steinheim Basin probably occured around 14 Ma some 0.8 Myr after the ~ 14.81 Ma Ries impact event Geographic and geologic situation in the study area in southern Germany Marked by red stars are outcrops of the Ries seismite within a distance of up to 205 km from the Ries crater and the proposed Steinheim seismite (orange stars) within a distance of up to 100 km from the Steinheim crater Four localties in green are presented and discussed in this study and are marked with stars half in red and orange Note that no seismite occurences caused by Alpine seismotectonic events are known North of the dotted line which we interpret as evidence for a second high-magnitude earthquake in the region that occurred subsequent to the Ries earthquake some doubt remained with respect to the impact-earthquake origin of the dike the upper end of the dike is not (unlike the Ries seismite capped by distal Ries ejecta) overlain by a diagnostic Steinheim-impact layer as is expected at the long distance from the relatively small source crater cannot be easily correlated laterally with the subhorizontal deposits of the Ries seismite and overlying deposits both the dike attributed to the Steinheim-earthquake and the Ries seismite occur as far as ~ 100 km from the two impact structures the most important innovation in this follow-up study refers to the biostratigraphic context of the fossil content in deposits below and above the seismite horizons within the newly described outcrops and the biostratigraphically determined relative age of the crater lake deposits in the Ries and the Steinheim impact structures Schematic description of the sedimentological situation (left) and event stratigraphic interpretion of the sedimentologic succession (right) in the Dietenwengen sand and gravel pit (near Eberhardzell ~ 2 km east of the Hochgeländ plateau; outcrop no the effects of the seismic event linked with the Steinheim impact are represented by slumps and ball-and-pillow structures within the upper seismite unit (all photographs taken by V.J.S Photographs of the details of the Steinheim seismite and clastic dikes from the four outcrops discussed in the present study; (a) The 4–5 m-thick Steinheim seismite in the Ziemetshausen sand pit with slumps in the upper parts and convolute bedding in the lower parts of the seismite in 2008; photographs: (c)and (d) were taken by V.J.S Fossils of this cervid with forked antlers are restricted to the European Land Mammal Zones (ELMZ) MN 5 and MN 6 but become increasingly abundant in MN 6 (evolution level Sansan) The findings of Dicrocerus in a relative high lithostratigraphic position indicate the upper seismite horizon in this outcrop can be biostratigraphically placed most likely in the MN6 biozone the seismite unit is overlain by several metres of undisturbed OSM sands topped by Quaternary deposits and soil the upper seismite horizon is often directly underlain or replaced by 3–4 m (depending on the mining situation) of cross-bedded sands with several internal layers that contain reworked OSM deposits with larger clasts and fossils of plants The upper seismite horizon is followed by a ~ 14 m-thick sequence of undisturbed as well as faults along which variable offset of the Molasse deposits can be observed These yellowish sands (‘gelbe Molasse’) are followed by a few metres of grey OSM deposits (‘graue Molasse’) that form the upper end of the sand and gravel pit The thin subvertical dikes and wedges in the cross-bedded sands on top of the upper seismite horizon may have been caused either by the overburden of glaciers during the Pleistocene or may have formed simultaneously with the upper seismite horizon but well preserved carnivore tooth (M 1 inf.) which fits morphometrically very well with the rare taxon Alopecocyon cf an extinct relative of the small red panda (fam Ailuridae) that today inhabits the Himalayas and SW China Fossil remnants of the carnivor genus Alopecocyon are only known from very few localities in mid-Miocene deposits (e.g Göriach) in Europe and Pakistan that span the ELMZ MN 6 and MN 7 biozones The faunistic and biostratigraphical element of Alopecocyon is crucial for dating the upper seismite horizon at the Dietenwengen locality we argue the dikes/sills and the convolute bedding in the upper seismite horizon are of mid-Miocene age and the result of the same seismic event the upper seismite seems to indicate an age corresponding to biozone MN 6 or the transition zone MN 6/7 the relatively thick and very distinct upper seismite horizon detected at the Dietenwengen sand pit is underlain by bone beds that offer a rich fauna indicative for the transitional ELMZ zone of MN 6 to MN 6/7 The lowermost Ries crater lake deposits are dominated by the same faunal assemblage The upper seismite horizon is under- and overlain by faunal elements of the ELMZ MN 6 to MN 6/7 strikingly consistent with identical faunal elements that occur in the lowermost Steinheim crater lake deposits; ELMZ European Land Mammal Zone It is noteworthy that none of the clastic dikes that cross-cut the Ries seismite/distal ejecta-couplet also cross-cut the upper seismite horizon This suggests the clastic dikes and the upper seismite produced by a second large Middle Miocene earthquake the paleoearthquake that produced the upper seismite potentially also created the clastic dikes Simplified lithostratigraphic columns illustrating the four outcrops described and discussed in the present study a lower Ries seismite horizon capped with distal Ries ejecta (or equivalent) and an upper Steinheim seismite horizon (or equivalent) are clearly associated by appearance and altitude above the sea-level Note that the outcrop Ziemetshausen with significant divergent altitude is situated ~ 50 km north of the other three outcrops and the grey arrow shows the potential maximum influence of the seismotectonic feature of the Hohenzollerngraben The seismotectonic source of the Upper Rhine Graben with its distance of more than 150 km to the Hochgeländ area and more than 200 km to the Ziemetshausen outcrop is not considered because seismite formation at such a distance is very unlikely Note that no other seismic source beside the Ries and Steinheim impact events had the potential seismic capacity to impart enough energy into the Ziemetshausen sedimentary target sufficent to form metre-thick seismite horizons the Ziemetshausen area is still situated far beyond the sphere of influence (at least 50 km) from all seismic sources thought to have been active in the Middle Miocene This makes the scenario of a tectonic or volcanic seismite-producing event in the study area very unlikely for the upper seismite horizon exposed in the Ziemetshausen sand pit the Ries and the Steinheim events both caused major seismic shaking and are both located only some 55 km away from this locality It is also noteworthy that the upper (Steinheim) seismite at Ziemetshausen located only ~ 53 km SE of the Steinheim crater is the thickest (4 to 5 m) and most distinctly developed upper seismite horizon in the entire study area whereas at other localities (in the Hochgeländ area and at Dietenwengen sand pit) the upper seismite horizons is developed less distinctly and only has a thickness between 0.5 and 2 m This indicates the seismic source for the upper seismite horizon was situated somewhere north of Ziemetshausen and not in the Alps in the South or in any major tectonic structure west of this area This agrees very well with the vertical extension and thickness of the clastic dikes that also decrease from North to South in the study area Although direct evidence for the context between the Steinheim impact and the formation of the upper seismite horizon and clastic dikes (e.g superimposed distal Steinheim ejecta on Steinheim seismite) still needs to be established the number and quality of biostratigraphic and geographic arguments provide a comfortable degree of certainty that the upper seismite horizon was most likely formed as a result of the Steinheim impact-earthquake We payed particular attention to ravines in the areas south of Ulm Outcrops with soft-sediment deformation structures and clastic dikes and sills were partially exposed below and above the distal ejecta horizon along the flanks of the ravines after very heavy rainfall in winter 2018/2019 in the Biberach and Ravensburg area and were first discovered and investigated in spring 2019 The structures were excavated during various field campaigns from spring until winter 2019 We excavated and examined in detail the sandy foreland basin deposits over a vertical extension of up to 20 m along the flank of some ravines in the Hochgeländ area (e.g. ‘Tobel Oelhalde-Nord’ near Biberach) and over tens of metres laterally along the flanks of the ravines in the Ravensburg area and in an active sand pit near Dietenwengen we discovered several new outcrops with Ries seismite overlain by distal Ries ejecta and dike swarms in the Hochgeländ plateau and near Ravensburg we finally discovered outcrops with two separate seismite horizons in a ravine in the Hochgeländ plateau (Josefstobel) The former Ziemetshausen sand pit was inspected in detail in the years 2005 and 2008 by members of our group and/or by colleagues mentioned as data source in

The previous DP-LSAP-Green coalition government had launched an initial climate change adaptation strategy in 2018. "But that was seven years ago, so it's time to revise the whole thing," said Wilmes, calling the updated plan an "adaptation of the adaptation strategy". Wilmes said the previous coalition government still lacked experience when it put together the 42 measures that made up the original plan, creating what he described as vaguely formulated plans and no indicators to measure progress. But the government is setting an increased number of targets this time around: 131 measures will figure in this strategy across 16 different areas to better prepare for extreme weather and other impacts of climate change. Among the solutions put forward are the planting of more trees and shrubs in public spaces and pushing renaturation efforts for rivers and streams. "We had almost no snow at all this winter," said Wilmes on Friday, explaining that this is a consequence of climate change. The number of measures in the strategy paper could increase significantly, Wilmes said, as he wants to receive feedback from the public on the plans. In the first consultation phase, which runs from February to March, experts from the public and private sectors will be able to take part in workshops on topics such as dealing with natural disasters and their financial consequences or the resilience of the food system. the general public will also be able to take part in the discussion Five workshops will be organised for - in Echternach (This article was first published by the Luxemburger Wort.

But Earth Day sent the clear message that the climate movement is still alive With the aim of creating an appealing brand the name of the “Domaine du Météore” winery near the town of Béziers in Southern France points to a local peculiarity: one of its vineyards lies in a round 200-metre-wide depression that resembles an impact crater scientists led by cosmochemist Professor Frank Brenker from Goethe University Frankfurt have now established that the crater was indeed once formed by the impact of an iron-nickel meteorite they have disproved a scientific opinion almost 60 years old because of which the crater was never examined more closely from a geological perspective Countless meteorites have struck Earth in the past and shaped the history of our planet that meteorites brought with them a large part of its water The extinction of the dinosaurs might also have been triggered by the impact of a very large meteorite Meteorite craters which are still visible today are rare because most traces of the celestial bodies have long since disappeared again This is due to erosion and shifting processes in Earth’s crust The “Earth Impact Database” lists just 190 such craters worldwide only three were previously known: Rochechouart in Aquitaine the Nördlinger Ries between the Swabian Alb and the Franconian Jura and the Steinheim Basin near Heidenheim in Baden-Württemberg (both in Germany) for laypersons the three impact craters are hardly recognisable as such Geologist and cosmochemist Professor Frank Brenker from Goethe University Frankfurt is convinced: the new meteorite crater will now extend the list the “Domaine du Météore” winery caught his attention One of its vineyards lies in a round depression about 220 metres in diameter and 30 metres deep and the proprietors use the scientific hypothesis that it is the impact crater of a meteorite – seemingly long disproved – as a marketing gag for their wine Although this hypothesis was proposed by several geologists in the 1950s it was dismissed by acclaimed colleagues a few years later Frank Brenker explains: “Craters can form in many ways and meteorite craters are indeed very rare I found the various other interpretations of how this depression could have formed unconvincing from a geological perspective.” That is why he and his wife collected rock samples for analysis in the labs at Goethe University Frankfurt – and indeed found the first signs of an impact crater Brenker: “The microanalysis showed that dark-coloured layers in one of the shists which usually simply comprise a larger percentage of mica might be shock veins produced by the grinding and fracturing of the rock which in turn could have been caused by an impact.” He also found evidence of breccia angular rock debris held together by a kind of “cement” which can also occur during a meteorite impact Professor of Applied Geophysics at Goethe University Frankfurt and a group of students with him to Southern France to examine the crater in detail They discovered that Earth’s magnetic field is slightly weaker in the crater than in the surrounding area This is typical for impact craters because the impact shatters or even melts the rock which can thus contribute less to Earth’s magnetic field With the help of strong magnets attached to a plate the researchers also found tiny iron oxide spherules of up to one millimetre in diameter Such spherules had already been found in other impact craters Later laboratory analysis showed that the ones here also contained nickel-bearing iron and encased a core of minerals typical for the crater environment the researchers discovered numerous shock microdiamonds produced through the high pressure during the meteorite’s impact Frank Brenker explains: “Such microspheres form either through abrasion of the meteorite in the atmosphere or only upon impact when a large part of the iron meteorite melts and then reacts with the oxygen in the air material shattered at the point of impact might then also be encased together with the lower magnetic field and the other geological and mineralogical finds allows us to draw hardly any other conclusion: a meteorite did indeed strike here.” This makes the crater very exciting for geological laypeople too because “every visitor can experience here the immense energies released upon such an impact.” Publication/Abstract: Frank E.
