摘要
通过对四川地区近百次地震震源机制结果的分析,研究了现代构造应力场对区域断裂类型及其活动方式的作用和影响。结果表明,四川地区强震的发震机制与区域断裂类型及其活动方式有着十分密切的联系。
In this paper, the function and effect of recent tectonic stress field on the type and active manner of regional fault were investigated by analysing source mechanism results of nearly one hundred earthquakes in Sichuan region. The results show that the occurring mechanism of strong earthquakes has a very close correlation with the type and active manner of regional fault in Sichuan region.
