| 摘 要： | 本文采用P、S最大振幅比资料测定中、小地震震源机制参数的方法,测定了澜沧—耿马地震前后震区182个中、小震的震源机制参数。并将这些结果结合大震及强余震震源机制P波初动解,对大震前后震区应力场方向的时空调整变化,以及序列的震源错动性质等进行了分析和讨论。

| Abstract: | The source mechanism parameters of 182 moderate and small events in the seismic area before and after Lancang-Gengma Earthquake have been determined by the method of P and S maximum amplitude ratio. Combined the obtained results with the P first onsets of the event and its strong aftershocks the temporal-spatial variation of stress field direction in the seismic area before and after the event and the source dislocation properly of the sequence have been analysed and discussed. |
