巨大津波の規模推定に関する基礎的検討

抄録

We examined to detect magnitude of TSUNAMI by the T-wave generated from earthquake. We presumed traveling underwater acoustic wave model of the Tohoku-Pacific Ocean Earthquake, and calculated the sound pressure level in the seismic center was 252dB (0dB=1μPa). If TSUNAMI happens near Japan, arriving T wave should be attenuated less than 55dB by propagation loss.
