On December 12,1992,5 : 29 a.m. UTC (1 : 29 p.m. local time), a magnitude M7.5 (USGS) earthquake struck the eastern region of Flores Island, Indonesia. A highly cooperative international survey team was formed, consisting of twenty scientists and engineers. Our Japanese team visited Indonesia on December 25,1992 to January 10,1993 and managed the field survey on earthquake and tsunami disasters. The first tsunami was reported to reach the shore of Flores Island within five minutes after the earthquake, because it is characterized as an extremely near-source event. About 1,000 people were killed by the tsunami. The maximum runup height measured is 26.2m at Kroko. Through the questionnaire the human behavior at the moment of tsunami attacking was studied. The lessons from the tsunami disaster will be useful for the Tokai tsunami prepardness in Japan.
