| 摘 要： | 通过对2007年6月3日滇西南宁洱6.4级地震前地震活动和前兆异常跟踪,震前对该地震作了短期预测.宁洱6.4级地震前,云南和滇西南地区的6级、5.8级以上地震出现了长时间的平静,显示了能量的积累过程;中期阶段4.5～5.0级地震在震中区周围形成了地震密集区,中、短期阶段滇西南地区MS≥3地震活动显著增强并形成空区,空区长轴250 km,计算震级为6.37,这与实际发生地震震级完全一致.滇西南地区的前兆异常显示,距离震源区近的以趋势异常为主,外围异常以突变为主.

| Abstract: | Through tracking the earthquake activity and precursory anomalies before Ning'er M6.4 earthquake on Jun.3,2007,the short-term prediction was done before the earthquake.There was long period MS6.0,MS5.8 earthquake calmness in Yunnan and south-west area of Yunnan province;MS4.5 to MS5.0 earthquakes formed seismic concentrating region around the epicentral area in the mid-term;MS3.0 earthquakes activity increased evidently and formed seismic gap in mid-short term.The magnitude calcucated from the seismic gap w... |
