Outline of Final Research Achievements |
Although analysis of crustal deformation has been intensively performed, most studies use analytical solutions with the assumption that the crustal structure is a half-space or a layered half-space, but some recent studies have used the 3D finite element method. This is because the heterogeneity of the crustal structure and ground-surface/layer-boundary geometry have a significant impact on simulation results. Crustal deformation analyses using high-fidelity crustal structure can be expected to consider such effects more realistically. The combination of computation results and crustal deformation observation data is expected to elucidate the earthquake mechanisms, which leads the reduction of earthquake disasters. With the accumulation of high-resolution observation data and the advancement of computer environment, the crustal deformation analysis method with such high-fidelity crustal structure data have been developed in this research project.
