地震,是由地壳构造运动内因产生的,是地应力活动与岩石抵抗力之间矛盾激化的结果.从活动展布情况看,多数地震发生在活动地块的边缘地带.这些地震,就是我们通常所说的构造地震,此外还有火山地震、塌陷地震、水库地震,爆炸地震等等.但不论何种地震,地下水均与之有密切关系、水库蓄水、油气田开采、深井注水等所诱发触发的地震,实质上都是水参与地震发动的结果.地下水在地震孕育发展过程中,既可增加力的作用,又可降低震源体的强度,使润滑性增强,使发震过程比“干”震源机制大大加快、而没有水的月球,构造月震每月只发生4—5次小震.
Earthquakes, which are caused by the internal cause of crustal tectonic movement, are the result of intensified contradictions between earth stress activity and rock resistance.According to the activity distribution, most earthquakes occur on the periphery of the active mass.These earthquakes are what we usually In addition, there are volcanic earthquakes, collapsed earthquakes, reservoir earthquakes, explosion earthquakes, etc. However, no matter what kind of earthquakes and groundwater are closely related to each other, the triggering triggered by reservoirs, oil and gas fields and deep well water injection Of the earthquakes are essentially the result of water participating in the earthquake.The groundwater can not only increase the force but also reduce the strength of the seismic source body so as to enhance the lubricity and make the earthquake process more “dry” Focal mechanism greatly accelerated, but without the water of the moon, the structure of earthquakes occur only 4-5 times a month minor earthquakes.
