Seismology for disaster prevention, Observational Seismology

Current Research

Japan is one of the active regions because Pacific and Philippine Sea plates are descending beneath the island arc. Many earthquakes occur in Japan. Our group is working on seismic studies for the prevention and mitigation of disasters. Research of crustal and mantle structures in this region is very important to understand the cause of earthquake and dynamics of subduction zones. Our group is working on the research to reveal the dynamics of the subduction zones and island arc regions by seismic observations considering tectonic background.
