马衔山北缘断裂西段6.5级地震对兰州市及周边地区的影响
|
摘要
位于兰州市南侧NW走向的马衔山北缘断裂是发生强烈地震最危险的地段。本文采用混合震源模型和随机合成高频地震动方法,研究了该断裂西段发生6.5级地震可能引起的兰州市及周边地区的地震动分布,给出了PGA分布图。
The Maxianshan north margin fault with strike NW crossing through south of Lanzhou city is the most dangerous place for a future strong earthquake to the city.Using the hybrid source model and the method of stochastic synthesizing high-frequency ground motion,the strong ground motion field in Langzhou city and its vicinity from an earthquake with magnitude 6.5 on the western segment of the fault is forecasted in this paper,the spatial characteristics and pattern of the field is summarized.
