| 摘 要： | 利用四川2015模型,选择Msdp嵌入的几种常用定位方法对九寨沟M_S7.0地震进行重新定位,比较震源深度结果,并用PTD方法验证合适的震源深度,从而得到较为可靠的震源深度。本文最终判定九寨沟M_S7.0地震震源深度为12±2km。

| Abstract: | The seismic intensity of the Jiuzhaigou MS7.0 earthquake is 9 degree, but the damage on the surface is relatively small, and the far field feel is relatively strong, and relatively accurate to determine the focal depth. The paper studies the 2015 Sichuan model and several commonly used embedded Msdp seismic location method to re position the Jiuzhaigou earthquake. The focal depth comparison results show that the PTD method can be used to verify the appropriate focal depth, and obtain the more reliable focal depth. The final focal depth is determined to be about 12km±2km. |
