Integration of Field Observations With Forward and Inverse Modeling for Tsunami Reconstructions Along the Fjord‐Dominated Coastlines of Northern Cascadia
Application of forward and inverse modeling of the 1964 Alaska tsunami indicates that inverse modeling underestimates flow depth TSUFLIND-derived flow characteristics are an important constraint ...

18 ka old #glacial features: Lithics transported at the base of a glacier polished the underlying rock surface of the #Molasse conglomerate #Nagelfluh, creating asymmetric #whalebacks #Rundhöcker which indicate the direction of the advancing glacier (here: right to left). #Allgäu

Unique #karst #landscape at the #Gottesackerplateau. #Karstification (dissolution related to precipitation) created bizarre #exokarst features in the #Schrattenkalk limestone: #karren fields #Rillenkarren #Rinnenkarren #Firstkarren #Rundkarren #sinkholes #furrows #grooves #clefts #HoherIfen

Fantastic example of #calcareous #sinter #tufa at #Lingenau #Vorarlberg #BregenzerWald #Austria. Freshwater #calcium #carbonate precipitates on the slopes below a calcareous 'petrifying' spring, #incrusting leaves and branches with a rate of 20 mm/yr! #Kalksinter #Quelltuff

61 years ago, on May 22nd 1960, the strongest #earthquake ever recorded (M 9.5) caused a trans-Pacific #tsunami. This field photo shows the sedimentary evidence of its inundation in central #Chile - in addition to the deposit of the 2010 Chile tsunami. #Terremoto1960 #Valdivia #22demayo1960

Prime example of #degassing of CO2 in a tectonic active region: The #Egergraben #Rift System is part of the European Cenozoic Rift System and active since Tertiary times. #Earthquake swarms, #mofettes and hot springs are evidence of the #magma reservoir and movement of fluids. #Soos #EgerRift

Yesterday’s “Schnupperuni” (girlsday) at UniBonn was real fun! Hope that we were able to catch the girls’ interest for geosciences with a short rock tutorial and the simulation of viscous landslide behavior. #UniBonn #Schnupperuni #girlsday #experiment #landslide
