水口水库诱发地震特征与发震断裂的探讨
|
摘要
基于水口水库诱发地震震源机制解及震中时空分布特征,探讨了水口水库诱发地震的发震断裂。通过对ML4.1地震及后期地震震源机制解的对比,认为ML4.1地震的发震断裂为北西向的闽江断裂带。
On the basis of the focal mechanism and the epicentral distribution characteristics of the induced earthquake of Shuikou reservoir,the seismogenic faults are analyzed.Comparing the focal mechanism solution between Shuikou reservoir ML4.1 earthquake and latest earthquakes, it is recognized that the seismogenic tectonic of the largest earthquake (ML 4.1) is the NW Mingjiang fault.
