| Outline of Final Research Achievements |
We studied the geometry of the Philippine Sea Plate that subducts from the Nankai Trough and the mechanical properties around its plate boundary. The plate subduction in the area around Ise Bay is a very shallow angle and it is necessary to evaluate the influence on the occurrence of the earthquake. We acquired data by establishing new observation seismic and GPS network in the area around Ise Bay to obtain the information on plate geometry and mechanical properties as well as seismic wave analysis and constructing a model in finite element method. Especially regarding the shape of the plate, we obtained the result supporting the possibility that the lower crust and the plate top are in contact beneath the Nobi Plain, which is located to the north of Ise Bay. In the deep part of the plate, we obtained results suggesting the involvement of high pressure fluid on the occurrence of low frequency earthquakes.
