The earth plate and plate squeeze and collision between each other, causing the plate edge and plate internal dislocation and rupture, resulting in the earthquake!

Earthquake, also known as ground motion or ground vibration, is a natural phenomenon caused by the rapid release of energy in the Earth’s crust, during which seismic waves are generated.

Details

01

The first is tectonic earthquake.

Tectonic earthquake is an earthquake caused by dislocation and rupture of rock strata in the deep underground.

02

The second is volcanic earthquakes

Volcanic earthquakes are earthquakes caused by volcanic action, such as magmatic activity, gas explosions, etc., and volcanic earthquakes can occur only where there are volcanoes, and the proportion of such earthquakes only accounts for about 7% of earthquakes in the world.

03

The third is collapse earthquake

A collapse earthquake is an earthquake caused by the collapse of an underground cavern or the top of a mine. The scale of such earthquakes is relatively small and the number of times is small. Generally, they only occur in limestone areas with dense karst caves or large-scale underground mining areas.

04

The fourth is the induced earthquake.

Induced earthquake is caused by reservoir water storage, oil field water injection and other activities. Such earthquakes also occur only in certain specific reservoir or oil field areas.

05

The fifth is artificial earthquake

Artificial earthquake is caused by human errors such as underground nuclear explosion, explosive blasting earthquake.
