摘要

Numerical simulation of seismotectonic tsunamis usually starts with specification of the initial elevation of the water surface in the tsunami source. The initial elevation is traditionally set equal to the vertical residual bottom deformation resulting from earthquakes. We discuss the imperfectness of the traditional approach and suggest an improved practical method of calculating the initial elevation from the solution of the 3D problem in the framework of potential theory. The method takes into account horizontal and vertical components of bottom deformation and bathymetry in the source area. Within the assumption of instant tsunami generation the suggested method represents the optimal way to specify the initial condition in the tsunami propagation problem. The tsunamis in the Central Kuril Islands on 15 November 2006 and 13 January 2007 are taken as examples to demonstrate the efficiency of the new method.
