By continuing you agree to the use of cookies. Effects of an earthquake. Seismic shaking is a major trigger for sediment redistribution in subduction zones, and clouds of dilute suspended sediment have been reported in association with large earthquakes. Rock slides are most often super-critical and the resulting tsunamis are determined by the frontal area of the rock slide, the impact velocity of the rock slide on the water body, the permeability of the rock slide, and the bathymetry. The landslide simulation study area, roughly covers the area depicted in the lower panel, Both the linear shallow water model and the disper-, sive version of GloBouss were used in the tsunami, The initial landslide geometry is shown in, tional slide masses are thinner, but cover a much, larger area.
