在我国近年来多次强震的总结中,逐渐形成了一个印象——地震前兆特征的个性很强,例如,同样发生在华北地区的海城地震和唐山地震,其前兆特征差异甚大。1982年9月在北京举行的大陆地震活动和地震预报国际讨论会上,我们不无意外地发现,凡开展地震预报研究十年以上、有较多观测点的国家,对如何搞地震预报具有相近的思路,其中包括对强震前兆基本特 In the summary of many strong earthquakes in recent years in our country, an impression has gradually emerged that the character of the earthquake precursors is highly individualized. For example, the Haicheng earthquake and the Tangshan earthquake, also occurring in North China, differ greatly in their precursor features. At the International Symposium on Earthquake Activity and Earthquake Prediction in Mainland China, held in Beijing in September 1982, we did not accidentally find that any country that has more observation sites for earthquake prediction for more than ten years and has more observation points has similarities with how to engage in earthquake prediction Train of thought, including basic special earthquake precursors
