云南地震前兆与短临预报

THE EARTHQUAKE PRECURSORS AND SHORT-IMPENDING PREDICTION IN YUNNAN

在云南地区近 30年前兆观测及其地震预测预报研究与实践的基础上 ,从映震效能的角度对云南地区的前兆观测进行了一次系统研究 ,从 6 4个前兆台站 16 8个观测项目中 ,优选出了 2 0个具有较好映震效能的前兆台项。它们初步构成了对云南地区地震进行“时、空、强”预测的骨干前兆指标群。

Based on the precursor observation and the research and practice of earthquake prediction in Yunnan region in recent 30 years, a systematic study on the precursor observation in Yunnan region is made from viewpoint of reflecting earthquake ability. From the 168 observation items and the 64 precursor stations, the 20 precursor items and stations with good reflecting earthquake ability are chosen, which have constituted preliminarily key precursor index groups for predicting the time, space and strength of earthquakes in Yunnan region.
