Sturm trotz Flaute: Tsunamis auf dem Vierwaldstättersee

Abstract: Storms on lakes are generally associated with wind. The severest storm observed on the Swiss Lake Lucerne, however, took place during calm and clear weather in the year 1601. During a magnitude 6.2 earthquake wave heights up to four metres were witnessed. High-resolution reflection-seismic imaging and coring of the lake's sediments revealed more than 15 coeval slide deposits associated with the 1601 earthquake. The largest slide affected an area of more than six square kilometres and left a distinct scar on the subaqueous slope. Numerical modelling suggests that water displacement from submarine landslides was the wave-generating mechanism. Slide horizons still deeper in the lake's subsurface indicate that other earthquake/tsunami events similar to those in 1601 have occurred in the past 15000 years.
