摘要
使用地震频次及其变化,平均震级和地震加权和的变化作为地震流函数研究了发生在1980-1989年期间中国大陆的6级强震前的地震概率增长时间(TIP)。结果表明,10次强震中9次发生在TIP之后,而且最长TIP为3.5年,TIP总时空占有率为30%。用同样的原则对新区进行识别也获得了好的结果。
The times of increased.probability (TIPs) of strong earthquakes(M=6 or so) occurred from 1980 to 1989 in mainland of China have been studied,using earthquake flow functions such as seismic frequency and its change,average magnitude change and change of weighted sum of main shocks in time intervals.The result shows that most of strong earthquakes occurred in the TIPs,and total TIPs take about 30% of the total space-time domain considered.
