Research note Since I am currently a member of the Nuclear Subcommittee of the Shizuoka Prefectural Science Council for Disaster Prevention and Nuclear Energy, I am deeply considering the mechanism of earthquakes

After 3.11 eaarthquke, I have been thinking about what was the reason why TEPCO could not predict Mw=9.0 as the design basis seismic ground motion in the application for safety review.
