Abstract

The 2011 Great East Japan Earthquake (GEJE) has shown that tsunami disasters are not limited to inundation damage in a specified region, but may destroy a wide area, causing a major disaster. Evaluating standing land structures and damage to them requires highly precise evaluation of three-dimensional fluid motion – an expensive process. Our research goals were thus to develop a coupling STOC method [1] and CADMAS-SURF/3D [2] to efficiently calculate all stages from tsunami source to runup and to verify their applicability. We confirmed the method’s accuracy by computing in the Onagawa District during the GEJE and comparing results to observed data. We also investigated the stability of buildings.
