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 research and practice of precursory meteorological observation and its prediction and forecast in the past 30 years in Yunnan Province, a systematic study of precursory observation in Yunnan Province has been carried out from the perspective of reflection seismic efficiency. From 16 observation stations , 20 precursors with better mappings performance are preferred. They initially formed a group of precursors to predict the “time, space and time” of earthquakes in Yunnan Province.
