云南文山5.3级地震跨断层形变短期前兆研究
ON SHORT-TERM PERIOD PRECURSORS OF CROSS-FAULT DEFORMATION BEFORE WENSHAN Ms5.3 EARTHQUAKE
【摘要】 将云南东部的断层网络视为一个互有关联的动力学系统,利用蕴震系统信息合成方法对该系统15条跨断层短水准和14条短基线资料进行处理与分析,结果表明:2005年8月云南文山5.3级地震前,断层形变短期异常明显,且水平运动异常较垂直运动更为明显。
【Abstract】 The fault network in the east of Yunnan can be regarded as a correlative dynamic system.From there 15 cross-fault short leveling and 14 short baseline data are processed by ISSS(Information Synthesis of Seismogenic System). The result shows that short-term anomaly of fault deformation is obvious and the horizontal movement is move evident than vertical movement before Wenshan Ms5.3 earthquake in August,2005.
