<資料・研究ノート>1976年8月のミンダナオ島南部の地震と津波について

Abstract

The southern part of Mindanao, the Philippines, was affected by an earthquake and tsunami on 17th August, 1976. In Japan, the earthquake was recorded by the Japan Meteorological Agency, but no effect were experienced. In the Philippines, a PAGASA (Philippines Atmospheric, Geophysical and Astronomical Services Administration) team commenced a survey just after the occurrence of the earthquake. Several private foreign teams also assisted, but there was no Japanese team. A preliminary report on the earthquake has been completed by Dr. Roman L. Kintanar, Administrator of PAGASA. Using this report, "The Moro Gulf Earthquake of August 17th, 1976, " I will give the survey results. This is followed by a statistical analysis aimed at estimating the risk of tsunamis and obtaining criteria for countermeasures, referring to the detailed catalogs of tsunamis presented by Iida et al. (1967) and by Soloviev and Gao (1973).
