摘要
对1984～2002年滇西北丽江、永胜、下关、剑川4点计8条跨断层短基线测边群体异常基本特征、群体异常信息提取方法、计算结果的预报意义进行了研究。结果表明跨断层短基线群体异常是物理力学意义清楚,对应概率比较高的本区成组强震短期预报指标。
The basic features,extracting method of anomaly information and prediction significance for the group anomaly from the measurement data of 8 cross-fault short baseline at Lijiang,Yongsheng ,Xiaguan and Jianchuan survey points in northwest Yannan Province,from 1984 to 2002,are studied. The results show that the group anomalys is a short-term prediction index for grouped strong earthquakes in the region with clear physical sense and high corresponding probability.
