On ScS Waves of Deep Earthquakes observed near the Epicenter and their Applications

[摘要] In the present paper the author investigated the ScS waves of deep earthquakes occurred in Japan, and constructed their time-distance curves especially for the earthquakes of very small epicentral distances. The depth of the Earth's core from the surface was reexamined, and a method was devised to evaluate the epicentral distance and the focal depth of a deep earthquake from the readings of ScS_??_P and S_??_P at a single station. Also the author studied a peculiar appearance of the initial phases of the S wave of deep earthquakes.
