本文主要根据地震学理论和六十年代中期以来我国多震区Ms≥6.0级大震前小震活动频度增高异常的震兆图象,分析研究了其涨落峰、谷间的时间分布特点与大震发生时间的关系,提出了大震前的“震情三分律”方法。并进行了回顾性预报应用检验,同时还指出“前兆三分律”现象。
This paper mainly based on seismological theory and the seismic megasonics image of the anomalous increase of the frequency of small earthquakes before the Ms≥6.0 large-scale earthquake in the multi-epicenter area of China since the mid-1960s, analyzed the characteristics of the temporal distribution of its fluctuation peak and valley And the relationship between the time of the earthquake and the method of “the law of the third earthquake” before the earthquake. And a retrospective application of forecasting forecast, but also pointed out that the “precursor three law” phenomenon.
