Geographic and geologic situation in the study area in southern Germany, northern Switzerland and Austria. 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.
