Traces of the AD1755 and AD1761 “Lisbon” earthquakes (and witch) in the sediments of Hechtsee (near Kufstein, Austria)
At the same days of these two great earthquakes, striking observations were made on the small Hechtsee: High waves, inundation and deposition of mud on its coastline.

We search for sedimentary traces of the reported anomalous behavior of the lake by conducting the first reflection seismic survey and gravity coring, and complementing this data by multibeam bathymetric mapping (Daniel Innerhofer; Unit of Hydraulic Engineering, UIBK). This data are processed within the BSc thesis of Maximilian Schellhorn.
