Abstract

Damage statistics for the 1944 Tonankai earthquake (MJ=7.9) have been re-evaluated, and seismic intensity distribution in JMA scale (I) is estimated from the collapse rate of wooden houses from the new developed dataset. This covers almost the entire region of the affected area. The areas with I=7 was limited to a part of the Kikukawa city and a part of Fukuroi city in the Sizuoka prefecture, and a part of Nishio city in the Aichi prefecture. The dataset also detects the severe damage region by tsunami in the Mie prefecture. Death claimed a toll of 1183 totally from this event. Many victims originated in these areas, but more than 250 victims originated in the other regions, which are the Handa and the Nagoya cities in the Aichi prefecture, where many munition plants were located. The collapsed buildings in these plants were artificially paid no heed to earthquake disaster due to Second World War. A lesson learned is that not only the strong shaking and the tsunami due to the earthquake, but also the artificiality with a lack of policy killed many people in earthquake.
