Outline of Final Research Achievements

Fifty people were killed by the Kumamoto earthquake in 2016, and most of them were killed in the zone up to 3 kilometers from the Futagawa seismogenic fault. On the other hand, distribution of entirely collapsed houses extended up to more than ten kilometers from the fault. Several video cameras showed that houses were collapsed entirely within a few seconds at the points close to the fault. It is presumable that people lived in a house close to the fault had no time to make sheltering to move their bodies under tables. We may generally say that the distribution of mortality shows the location of the seismogenic fault more clearly than that of house damage. We confirm this fact for the 1927 Okutango Earthquake, the 1854 Anei Iga Ueno Earthquake, the 1828 Echigo-Sanjo earthquake, and another several earthquakes.
