| 摘 要： | 由地震Ｐ波初动符号资料，求解得到１９９５年１０月２４日武定６．５级地震序主震及２１外强余震的震源机制解。主震的两个节面走向分别为北西西向，倾向ＮＮＥ，倾角７０°；另一个节面走向为北北东，倾向Ｗ，倾角７７°；等效释放应力场主压力力方位为３２４°，仰角２４°。表明与区域应力场基本一致的主要震震源应力场及发震断裂控制着整个序列的地震活动。

| Abstract: | Unprecedentedly great deformation variation occurred at fixed point of Yongsheng seismostation and the deformation variation in WE direction was remarkably larger than that in NE direction before the Lijiang earthquake,which displays a typical earthquake example of striking varation of fixed point deformation near focla region before large earthquake with M 7 0, having imortant reference significace to researching anomaly characteristics near observation points before large earthquake in the future. |
