除地应力变形机理外，岩浆去气、油气活动也可能是产生地震的潜在重要的机理，而季节与气候变化等则可能是诱发地震的外部因素。地震虽是自然灾害，但它是形成矿产资源不可忽视的重要地质作用，且有助于人类探索地球深部奥秘，故加强古地震研究是地震活动规律研究不可缺少的重要环节。 In addition to geomechanical deformation mechanisms, magma degassing and hydrocarbon activities may also be potentially important mechanisms for earthquake generation. Seasonal and climatic changes may be external factors that induce earthquakes. Although the earthquake is a natural disaster, it is an important geological function that can not be neglected to form mineral resources and helps mankind to explore the deep mysteries of the earth. Therefore, strengthening the study of paleoseismicity is an indispensable and important link in the study of the law of seismic activity.
