Hillshade of the bathymetric map of Lake Thun and the sourrounding area. a Map of the study area showing the location of the airgun (black lines) and the pinger (red lines) reflection seismic lines and the position of the long sediment core (white star). Bold lines represent the reflection seismic profiles that are shown in Figs. 3, 4 and 5. The black triangle shows the slide impact location for the simulation of the impulse wave. A, B, C and D refer to the locations where wave run-up has been estimated. b Enlargement of the detachment area on land and the depositional area of the mass movement in the lake. The dashed white line marks the the deformation lobe (“amphitheatre”). c Lake bottom profile of the X–Y transect (position is shown with a white line in b).
