[30] The numerical simulation of dynamical process in the earthquake source performed in this work on the basis of keyboard model demonstrates that tsunami waves generated by different combination of keyboard block motions have an essentially different character what leads to different picture of distribution of maximum run-ups along the coast. Taking into account of oblique character of the subduction zone characteristic for 26 December 2004 Sumatra-Andaman earthquake gives a good agreement with run-up values observed at the Thailand coast. It is noted that such a model can more adequately account for the character of the wavefield in other regions of the Indian and the Pacific oceans also.
