浙江珊溪水库重复地震事件研究
A Study on Repeated Earthquakes in Zhejiang Shanxi Reservoir
摘要
Abstract
Repeated earthquakes always occur on the same fault, and have similar magnitude, focal mechanism and also high similar waveforms. Due to the same source and spreading path, the change of travel time can reflect the change of wave velocity in the medium, which in turn could be employed to measure the change of wave velocity in the crust. On the other hand, studying the repeatability of local earthquakes can explain the change of focal mechanism. This article processed the earthquakes sequence nearby Shanxi reservoir by using waveform correlation method, calculated the cross correlation coefficients, and selected the similar earthquake clusters with correlation coefficients ＞ 0.8 for research. It then analyzed similarity and repeatability of earthquakes in Shanxi reservoir and the application of repeated earthquakes.关键词
