TSUNAMI DANGER IN THE KERCH STRAIT

Abstract

The numerical simulation of the tsunami wave propagation along the Kerch Strait is carried out with localization of possible sources at the entrances to the strait, both from the Black Sea and from the Sea of Azov. Under computation of both generation and tsunami propagation, a system of nonlinear shallow water equations was used. The potential strong earthquakes (with earthquake magnitude M ~ 7) with seismic sources of elliptical shape were considered. Detailed assessments of the wave characteristics in the Kerch Strait, in particular for the Crimean bridge area, were carried out. The obtained wave characteristics are compared with the available data of the work of other authors.
