As several as 400,000 people could die, mainly in Pacific coastal areas from Shizuoka to Kochi prefectures, if a Nankai Trough triple earthquake happens, according to a new prediction by Kansai University Professor Yoshiaki Kawata.
Kawata, who unveiled the prediction Friday at a lecture in Osaka, mentioned a Cabinet Office study panel that he chairs will announce a similar prediction in late August.
A Nankai Trough quake is forecast to occur if the so-named Tokai, Tonankai and Nankai earthquakes strike simultaneously.
In 2003, the government’s Central Disaster Management Council predicted the death toll from a magnitude-8.7 triple quake would be about 25,000 at most.
After the Great East Japan Earthquake, the Cabinet Office raised the magnitude to 9 and unveiled in March its prediction of a Nankai Trough quake’s maximum seismic intensity and the height of ensuing tsunami.
The Cabinet Officeis now working on new predictions concerning casualties and other damage as a outcome of such a disaster.
