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."/>

Abstract 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.
