内容記述 | Intermediate-period P-wave records at far-field stations are analyzed to derive the focal depth and the source characteristics of the largest three aftershocks of the Japan Sea earthquake of May 26, 1983. Event A (June 9, 21 : 49, MJMA=6 .1) and Event B (June 9, 22 : 04, MJMA=6 . 0) occurred near the south edge of the source region of the main shock. Their focal depths are determined as 13 km and 12 km, respectively. Event C (June 21, 15 : 25, MJMA=A7 . 1) took place near the north edge of the source region. Its focal depth is estimated at about 8 km. The essential part of moment rate function for Event A is found to be expressed by a single pulse with a width of about 1 sec, while that for Event B is composed of two pulses separated in time. The moment rate function obtaine d for Event C consists of two pulses with nearly the same width of about 3.5 sec, and the time lag between them is estimated at 2.5 sec. | |||||||||
