| 摘 要： | 研究了1995年10月24日云南省武定6．5级强震前的地震活动性参数、空间分布图象、距震中135km的巧家台振幅比、波速比演化特征，结果表明武定6．5级地震孕育发生有明显的阶段性变化，经历了早期（1988年4月－1992年7月），中期（1992年8月－1995年3月），晚期（1995年4月－1995年10月）阶段的发展，最终发生了强震。最后应用岩石破裂实验结果，分析了武定6．5级地震孕震过程。

| Abstract: | This paper studies the seismicity parameter,space distribution pattern and amplitude ratio and Vp/Vs ratio from Qiaojia station 135 km from the epicenter before strong the Wuding earthquake with M6 5 on October 24,1995 in Yunnan Province.The results show that prepatation and occurrence of the Wuding Earthquake with M6 5 went through a clear stage variation,the early stage (from April,1988 to July,1992),the middle stage (from August,1992 to March,1995),late stage (from April,1995 to October,1995)and final earthquake occurrence.Lastly,the seimogenic process for the Wuding earthquake with M6 5 is analyzed through using the experiment results of rock rupture. |
