一、前言震惊中外的1976年唐山地震过去10年了,回顾往事,百感交集,地震前后发生的重要事件历历在目。为了纪念唐山地震10周年,为了悼念在唐山地震中以身殉职的六位同志,对唐山地震前的地震趋势预报作一简要的回顾。二、华北北部强震发生的地震地质背景和强震危险区预测为了进行华北地区的地震趋势预报,研究强震发生的地质构造条件和强震活动特征,并进行强震危险区预测和地震烈度区划,我们从1973年开始进行一系列地震地质方面的基础研究工作。后来,结合唐山地震的实践和认识,把这些成果分别发表在不同的论著中。尤其值得指出的是,由贾云车执笔写成的文献[1]是在唐山地震之
I. Preface The Tangshan earthquake shocked both at home and abroad in the past 10 years in 1976, recalling the past events, mixed feelings, the important events before and after the earthquake vividly. In order to commemorate the 10th anniversary of the Tangshan earthquake, in order to pay tribute to the six comrades who lost their lives during the Tangshan earthquake, a brief review of the earthquake tendency forecast before the Tangshan earthquake was made. Seismic Geological Background and Prediction of Strong Earthquake Hazards Occurred in Strong Earthquakes in North China and North China In order to predict the earthquake trend in North China, the geological structural conditions and the characteristics of strong earthquakes occurred in strong earthquakes are studied. The prediction of strong earthquakes and the intensity of earthquakes Zoning, we started in 1973 a series of basic research in the seismic geology. Later, combined with the practice and understanding of the Tangshan earthquake, these results were published in different works. In particular, it is worth pointing out that the document [1] written by Jia Yun-chang was written in the Tangshan earthquake
