摘要
常德地震是有记载的华南最大地震之一。在前人研究的基础上,采用内圈等震线几何中心法进行震中定位。分析地震发生的地质背景,用地震波传播的波导效应解释等震线形态及其它地震现象。同时,指出在常德市及周边地区的地震监防中应注意的问题。
The Changde earthquake is one of the largest earthquakes in Southern China. On the basis of previous studies, the inner geometric center method is used to locate the epicenter. Its geological background is analyzed and waveguide effect is used to interpret the morphology of the isoseismic line and other seismic phenomena. Meanwhile, we point out issues relevant to seismic monitoring and prevention in Changde and its surrounding areas.
