| Research Abstract |
Preparing for expecting future Nankai-trough earthquake the understanding of the detailed structure of the subducting Philippine Sea Plate is an important subject in the context of prediction of the stress accumulative process in a plate boundary, and mitigation of strong ground motions and tsunami.
For understanding the effect of heterogeneous structure of the Philippine Sea Plate on the development of strung ground motions radiating from the source at the top of the plate and guiding through the plate, this study was investigated from two viewpoints of study; 1) large-scale high-density computer simulation of seismic wave propagation using the Earth Simulator supercomputer, and 2) detailed analysis of dense seismic recordings of recent earthquakes obtained by high-density network in Japan.
