摘要
唐山地区地处华北陆块,属板内环境,唐山地震并不处在大断裂带上,构造地震理论很难解释唐山地震发生的原因。通过分析研究唐山地震的成因及各类特征,认为唐山地震与岩浆活动有关,可能属于隐爆地震,其中动物异常反应被认为是隐爆地震的重要特征之一,震前发生地下深部流体气体泄漏,是短临地震预报最明显、最重要的标志。本文深入探讨了隐爆地震形成的机理,构建了花岗岩侵位引发的隐爆地震模式图,认为中国各地发生的大地震可能大多属于隐爆地震而非构造地震。
The Tangshan earthquake was the most devastating natural disaster in modern Chinese history,and the lesson of the Tangshan earthquake's underreporting was written in blood.Exploring the causes of the Tangshan earthquake and avoiding another major earthquake disaster is an urgent and urgent task.Tangshan is located in an intraplate environment,inland areas,and the Tangshan earthquake is not on the major fault zone.The theory of tectonic earthquakes is difficult to explain the cause of the Tangshan earthquake.A large number of facts indicate that the Tangshan earthquake is related to magmatic activity,and it may belong to the category of hidden explosive earthquakes.An important basis for hidden explosion earthquakes is the abnormal response of animals,which is caused by the leakage of fluid and gas in the deep underground before the earthquake.It is the most obvious,important,and undisputed indicator of short-term earthquake prediction.The causes of earthquakes are very complex,and the vast majority of China is not located in plate tectonic activity zones.So far,most of the major earthquakes that have occurred in various parts of China may belong to explosive earthquakes rather than tectonic earthquakes.Therefore,it is urgent to study the theory and prediction methods of hidden explosion earthquakes.
