琵琶湖周辺の地震活動について

Abstract

Brief report is given about results of the observation of earthquake activities in the area aroundLake Biwa.Seismicity map has been made in that area last half year. And there is no characteristicactivities around the region of up-heaval as reported by Dr. Dan bara in the west coast along LakeBiwa.But near and along the large active fault, Hanaore, in parallel with the west coast line ofLake Biwa, there have been found many micro-earthquakes. Above result reminds of the rela-tion between Yamasaki fault and existence of many microearthquakes near it.In the area around Lake Biwa and its surroundings, many faults were developed in com-plicated manner. The observation, continued by several geophysical methods, will derive the newand more detailed results and conclusions.
