Аннотация доклада:
For description of dynamic processes in tsunami source 3D numerical model was developed. We consider a layer of an ideal compressible homogeneous fluid in the field of gravity. The layer is bounded by free surface above and by absolutely rigid bottom below. To find acoustic and gravitational waves generated by bottom displacements the linear problem for the current velocity potential is solved. Calculations are carried out in regions with real bottom topography (ETOPO2). The results of numerical modeling are compared with the data of bottom pressure measurements (JAMSTEC) in the Tokachi-Oki 2003 tsunami source.
