mega-thrust, Metropolitan Seismic Observation Network ( ), disaster mitigation

The Earthquake Research Institute, the University of Tokyo

A special project for earthquake disaster mitigation in the Tokyo Metropolitan Area is under-

way ( ). Assessment in Kanto of seismic hazards produced by the Philippine Sea Plate (PSP)

mega-thrust earthquakes requires identification of all significant faults, possible earthquake scenar-

ios, rupture behavior, regional characterizations of PSP geometry, physical properties of overlying

Honshu arc and local near-surface seismic site e ects. We are developing a dense seismic network

in the urban area with stations so far. Seismic images with improved spatial resolution beneath

the Tokyo Metropolitan Area are obtained to assess source areas of the coming large metropolitan

earthquakes.
