隐爆地震
|
摘要
隐爆地震是地下流体隐蔽爆破形成的。隐爆地震与断层地震在孕震构造、发震机制和震源动力等方面存在着显著的区别 ;与火山地震在流体性质、发震机制和震源深度等方面也存在着显著的区别 ,应划归为一类新的地震类型。隐爆地震可由高压流体、岩浆侵入、流体相变和天体撞击等作用引起。笔者认为 ,深入研究地下流体的变化规律 ,对有效预测地震具有重要的现实意义。
Hidden-explosive earthquake is triggered by the hidden explosion of underground fluid. Hidden-explosive earthquake is distinctively different from fault earthquake in the aspects of seismogenic structure, mechanism and motive force of earthquake. It is also significantly different from the volcanic earthquake in the property of fluid and the depth of seismic focus. Therefore this kind of earthquake should be classified as a new type of earthquake. Hidden-explosive earthquake can be caused by high-pressure fluids, magmatic intrusion, facies change of fluids and celestial body collision. The author believes that careful study on the rule of the changes of underground fluids is of importance for effective prediction of earthquake.
