DEVELOPMENTS OF AN AUTOMATIC SETTING SYSTEM OF INPUT DATA AND A LINKAGE SYSTEM FOR EARTHQUAKE SIMULATION AND TSUNAMI SIMULATION

Abstract

 This study aims to rationalize earthquake and tsunami simulation technology by automatically converting and integrating various data with different description formats (DPP). Specifically, a general-purpose ground model “GridModel” is created using borehole data and numerical elevation models available on the National Land Transport Data Platform, automatically converted into a 3-D finite element model with nodes and boundary conditions, and output as an input file for seismic response analysis software such as FLIP. We have also developed a program that automatically creates input files for T-STOC from the "Cabinet Office Nankai Trough Large Earthquake Model Study Group" data. Furthermore, we have tried to link these automatic input data generation programs to take into account the results of subsidence of the ground surface from seismic response analysis in the tsunami simulation.
