a MTDs and event horizons A to K on a seismic profile of Plansee. Black arrows indicate transparent megaturbidites with ponding geometries. Locations of seismic profile and core are shown in Fig. 1c. MTDs on seismic profiles correlate to amalgamated turbidites (red in b) in the sediment core. b Core lithology with amalgamated turbidites (red) and associated postseismic landscape response (grey) and 95% age range of calibrated 14C samples. Interpretation of qualitative earthquake intensities (grey-scaled stars) are based on postseismic landscape response33 and relative turbidite thickness34 explained in the main text. c MTD distribution and thickness maps for earthquakes EQ-B and EQ-C (Supplementary Table 2) demonstrate coeval failure of multiple hemipelagic (black arrow) and deltaic (white arrow) slopes (see Supplementary Figs. 7, 8). MTD maps of all event horizons are presented in Supplementary Fig. 9.
