Among the historical reports are Reviewed by: many tsunamis in Swiss lakes that have been triggered both by subaerial and subaqueous Emily Margaret Lane, mass movements (SAEMM and SAQMM). In this study, we present a simplified National Institute of Water and Atmospheric Research (NIWA), classification of lakes with respect to their relative tsunami potential. The classification New Zealand uses basic topographic, bathymetric, and seismologic input parameters to assess the Jia-wen Zhou, Sichuan University, China relative tsunami potential on the 28 Swiss alpine and perialpine lakes with a surface area Carl Bonnevie Harbitz, >1km2. The investigated lakes are located in the three main regions “Alps,”“Swiss Norwegian Geotechnical Institute, Plateau,” and “Jura Mountains.” The input parameters are normalized by their range and a Norway k-means algorithm is used to classify the lakes according to their main expected tsunami *Correspondence: Michael Strupler source.
