摘要
对2011年3月缅甸Ms7.2地震前云南地下流体前兆异常进行系统研究,结果表明,距震中540 km范围内共有14测点17个测项异常;异常时空特征表明,异常演化具有明显的阶段性,地震前5个月开始异常逐月增多,并有向震中收缩发展的迹象。
The systematic research of ground fluid precursory anomalies in Yunnan before Burma Ms 7.2 earthquake on March 2011 was done. The study results show that there are 17 items anomalies in 14 observation stations appeared before earthquake within 540 km from the epicenter. Temporal and spatial characteristics of anomalies shows that the anomaly evolvement displays obvious stage, anomaly begin gradually increase in five months before earthquake and seems concentrate to the epicenter.
