RECALL OF A MID-SHORT TERM PREDICTION BEFORE THE TANGSHAN EARTHQIAKE
【摘要】 1976年,作者及同事根据地震节线法画出了5个地震危险区,其中Ⅱ区1976年4月发生了和林格尔6.3级地震。又结合地应力和地磁资料,预测了7-8月份华北北部可能有较大地震。此文目的是纪念唐山地震20周年。
【Abstract】 In 1976,the author and his colleagues drew 5 seismic risk regions by seismic nodal line,among the others,in Ⅲ region occurred the Helingeer M 6.3 earthquake in April,1976.Combining with the stress and geomagnetic data,it was predicted that a relatively large earthquke might occur in July and Augustin 1976 in northern part of North China.The purpose of this paper is for the 20th anniversary of the Tangshan earthquake.
