摘要
2012年6月24日宁蒗5.7级地震发生前,地震活动性存在中期异常,地下流体存在中短临异常。地震活动性方面存在滇西地区5级以上地震东西迁移规律性活动、滇西地区4级以上地震成条带分布和程海断裂发生4级窗口地震等中期震兆异常。水氡、固体二氧化碳、水温和流量存在中短临前兆异常。地下流体前兆中期、短期和短临阶段都出现同步性异常。
There were some of anomaly changes from the data of seismicity and underground fluid before the 2012 Ninglang M5.7 Earthquake. The character is seismic position shift with the seismic magnitude 5.0 from the eastern part to the western. Another character is middle- and short-term change anomalies of underground water contents.
