SOME PROPERTIES OF MICROEARTHQUAKES IN THE WESTERN PART OF KINKI DISTRICT (PRELIMINARIES)

Properties of microearthquakes in the western part of Kinki District were investigated. The analysis was mainly made as to about 30 earthquakes observed simultaneously at three stations. Distributions of epicenter and focal depth seem to have some particular characteristics in the area concerned. Some phenomena suggesting the future development were described as to the magnitude and focal mechanism. Also, the distributions of P-S time and maximum amplitude at three stations were mentioned
