水库诱发地震讨论及其动力学机制分析

A Discussion on Reservoir Induced Earthquakes and Their Dynamic Mechanism

本文介绍了几个典型水库地震事件,总结了目前对水库诱发地震的分析方法及其依据,重点从地震发生的时间、空间、强度、活动特征、震源深度5个方面介绍了水库诱发地震的特征,最后简要分析了水库诱发地震的动力学机制,认为通过人为调整库水载荷大小等因素来研究水库地震活动性,对于研究地震触发及地震预报等有重要的社会价值和科学意义。

This paper introduces several typical reservoir-induced earthquakes(RIE)in China and abroad,and briefly summarizes the present analysis methods and their basis of the study on RIE.The present review also sums up the characteristics of RIE in the following five aspects:the seismic occurrence time,the seismic space distribution,the seismic intensity,the seismic activity characteristics and the depth of seismic focus.The paper finally gives a brief analysis of the dynamical inducing mechanism,and put forward the view on the seismic activity research by regulating the water load.This will provide important social values and scientific significance for more research on the tectonic earthquake triggering and prediction.
