内容記述 | The frequency of microearthquakes observed by HES 1-0.2 electromagnetic seismograph (Vmax.=150,000) at Tsukuba Seismological Observatory (MTJ) was investigated for different interval of S-P time for the period from August 1969 to October 1973. The frequency of microearthquakes are stationary with some fluctuations for the intervals (A-H), however it shows a decreasing tendency for the interval lc). Abnormal events such as earthquake swarm and aftershock activities are clearly observed in Fig.1, (B), (C) and (E). | |||||
