FIELD SURVEY OF THE EAST JAVA EARTHQUAKE AND TSUNAMI OF JUNE 3, 1994

A field survey of the June 3, 1994 East Java earthquake tsunami was co nducted within three weeks, and the distributions of the seismic inten sities, tsunami heights and human and house damages were surveyed. The seismic intensities on the south coasts of Java and Bali Islands were small for an earthquake with magnitude M 7.6. The earthquake caused n o land damage. About 40 minutes after the main shock, a huge tsunami a ttacked the coasts, several villages in East Java Province were damage d severely, and 223 persons perished. At Pancer Village about 70 perce nt of the houses were swept away and 121 persons were killed by the ts unami. The relationship between tsunami heights and distances from the source shows that the Hatoris tsunami magnitude was m = 3, which seem s to be larger for the earthquake magnitude. But we should not conside r this an extraordinary event because it was pointed out by HATORI (19 94) that the magnitudes of tsunamis in the Indonesia-Philippine region generally exceed 1-2 grade larger than those of other regions.
