摘要
在对华北邢台、渤海、海城、唐山、大同五大震例的各前兆学科震后变化进行分析的基础上,本文归纳出综合判断后续地震异常的3项定量指标与4项定性指标,还给出了模糊综合评判的方法并计算出符合实际的结果,当评判有震时又给出预报后续地震三要素的经验性判据.
In this paper,based on the analysis of various changes of all precursor observational means after the Xingtai, Bohai,Haicheng, Tangshan and Datong earthquakes in North China area, 3 quantitative indexes and 4 qualitative indexes have been summed up. Besides, the method of fuzzy synthetic evaluation has been given. The results calculated by this method conform to reality. When the result of evalution is that there will be an earthquake, the experiential criterion for the three elements of follow - up earthquakes has been given.
