综合分析兴文MS5.7地震672个余震的精定位结果、应力背景和深部背景认为,兴文MS5.7地震是由北东-南西向隐伏断层所引起。北西-南东向的水平最大主应力持续挤压引发破裂,形成MS5.7主震;其他3次地震与兴文MS5.7地震呈北东向线性排列,结合震源机制解和应力方向分析认为,其他3次地震也与该隐伏断层有关。"/> Seismotectonics Environment Analysis of Moderate-Strong Earthquakes in Southern Sichuan Basin: A Case of Sichuan Xingwen MS5.7 Earthquake" /> Analysis of 672 aftershocks, stress background and deep background of the Xingwen MS5.7 earthquake, shows that it was caused by the northeast-southwest buried fault. The horizontal maximum principal stress of the northwest-southeast direction continues to squeeze and caused Xingwen MS5.7 earthquake. Three other earthquakes and the Xingwen MS5.7 earthquake are linearly arranged in a northeast direction. Combining focal mechanism solution with the stress direction suggests that the other three earthquakes are also related to the buried fault."/> 川南中强震地震构造环境分析——以四川兴文M<sub>S</sub>5.7地震为例
