地震的起因中英文介绍

导语:地震又称地动、地振动，是地壳快速释放能量过程中造成振动，期间会产生地震波的一种自然现象。地球上板块与板块之间相互挤压碰撞，造成板块边沿及板块内部产生错动和破裂，是引起地面震动(即地震)的主要原因.



地震的起因英文介绍

The causes of the earthquake 地震的起因

The earthquake causes the Earth's surface vibration There are many reasons according to the causes of earthquakes, earthquakes can be divided into the following:

引起地球表层振动的原因很多，根据地震的成因，可以把地震分为以下几种：

1. Tectonic earthquake

Since the depths of underground rock dislocation, caused by the rupture of the earthquake known as tectonic earthquake. Such earthquake occurred most often, the greatest damage, the earthquake accounted for about 90 percent of the world over.

1.构造地震

由于地下深处岩层错动、破裂所造成的地震称为构造地震。这类地震发生的次数最多，破坏力也最大，约占全世界地震的90%以上。

2. Volcanic earthquake

As the volcano, such as magmatic activity, such as gas explosions caused by the earthquake known as the volcanic earthquake. Only in areas of volcanic activity may occur before the volcanic earthquakes, such earthquakes around the world accounts for only about 7 percent of the earthquake.

2.火山地震

由于火山作用，如岩浆活动、气体爆炸等引起的地震称为火山地


震。只有在火山活动区才可能发生火山地震，这类地震只占全世界地震的7%左右。

3. Earthquake collapse

As the top of underground caves or mine collapse caused by the earthquake known as the collapse of the earthquake. Such relatively small-scale earthquake, the number of little, if any, tend to occur in the limestone cave over the region or large-scale underground mining of the mining area.

3.塌陷地震

由于地下岩洞或矿井顶部塌陷而引起的地震称为塌陷地震。这类地震的规模比较小，次数也很少，即使有，也往往发生在溶洞密布的石灰岩地区或大规模地下开采的矿区。

4. Induced earthquake

As water, oil field activities such as water flooding caused by the earthquake known as the earthquake-induced. Such earthquake only in certain oil reservoir area or region.

4.诱发地震

由于水库蓄水、油田注水等活动而引发的地震称为诱发地震。这类地震仅仅在某些特定的水库库区或油田地区发生。

5. Artificial earthquake

Underground nuclear explosions, explosives, blasting and other human-induced ground vibration known as the artificial earthquake. Artificial earthquake was caused by human activities in the earthquake. Such as industrial blasting, the vibration caused by underground nuclear explosions in deep water in a high-pressure water and the large increases the pressure on the crust, sometimes induced earthquake.

The seismic wave origin, called the source. Source on the ground of the vertical projection, called the epicentre. The depth of the epicentre to the source called focal depth. Usually focal
