We also found large ground motion in the mouth of the Fujikawa river due to the rupture directivity effects of the segment of the Fujikawa-kako fault zone. We are devoted to creating web sites, educational curriculum, graphic design and fine art which reflect the great creativity evident in both human endeavor and the natural world. Large ground motion can be identified in the southwestern part of the area. Interactive Earth has been developing interactive media since 1993. We conducted a hybrid simulation of broad-band strong ground motion in the eastern part of Shizuoka prefecture and the southern part of Yamanashi prefecture due to the scenario earthquake using a 3D subsurface structural model of deep sedimentary layers. A joint rupture of two segments of the Fujikawa-kako fault zone and the Philippine Sea plate boundary along the Suruga trough was used in the strong motion prediction. The possible scenarios were assumed from discussions with geoscientific researchers in the project. This paper reports on some of the results of the engineering seismological researches in the project including strong motion prediction due to the future events in the area. The results of the microtremor explorations were reported in Yamanaka et al.
Many geophysical explorations have been conducted to know velocity structure of the shallow and deep sediments in the area. We were contributed in the engineering seismological topics related with site characterization for seismic hazard in the area and prediction of earthquake ground motion for the possible earthquakes in the area. The research group consists of 6 sub-groups for geological and geomorphological studies on active faults, seismic activity, historical earthquake study, engineering seismological study and communication with local governments.
A research project had been conducted to obtain geoscientific data on earthquake mechanisms, geological features, and engineering-seismological knowledge on possible earthquakes. The fault is located in the northern extension area of the Philippine Sea plate in Suruga Bay.
Fujikawa-kako fault in central Japan is one of the most active faults in Japan.
