| 摘 要： | 分别利用近震波形反演求解震源机制解的gCAP方法和全波形反演方法反演了鲁甸MS6.5地震的震源机制解，并比较两种方法的优点与特性。结果发现，数据方位角的覆盖范围会影响解的稳定性，在使用gCAP方法时尤其需要注意；两种方法获取的震源机制解结果较为一致，走向为73°~77°，倾角为72°~85°，滑动角为157°~180°。

| Abstract: | In this article, we briefly review the gCAP (general cut and paste) and the full-waveform inversion focal mechanism solution inversion theories using the regional seismic waveform. These methods are applied to the focal mechanism solution inversion of the Ludian MS6.5 event. The main idea of this work is to evaluate the reliability of the inversion results and to compare the two methods in real data application. According to the comparison, we find that the bad azimuthal coverage decreases the reliability of inversion results. In conclusion, the source mechanism is strike 73°-77°, dip 72°-85°, and rake 157°-180°, inversed by gCAP and full-waveform method. |
