Earthquakes are generated, evolve and move around the Earth’s surface crust in a continuous process that eventually causes earthquakes.
Earthquake is a kind of natural disaster, and it often brings great harm to human beings. So how is it caused? Let’s find out together.
Tectonic earthquake: is because of the fault rock, resulting in displacement displacement, in the geological structure, the formation of great changes caused by the earthquake, also known as fault earthquake.
Volcanic earthquake: It is the energy shock emitted by a volcanic eruption, causing the earth’s crust to shake. Volcanic earthquakes are also sometimes strong. But the earthquake spreads tens of kilometers near the volcano.
Collapse earthquake: An earthquake caused by the collapse of a stratum. The number of such earthquakes is relatively small, accounting for only about 3% of the total number of earthquakes. Usually, the magnitude is small and the damage is not large.
Induced earthquake: An earthquake that is triggered by some factor outside the earth’s crust in a specific area, such as meteorite falling to the earth, reservoir filling, deep well filling.
Artificial earthquake: by underground nuclear explosion, the implementation of explosive blasting and other human factors, caused by the ground vibration called artificial earthquake. Artificial earthquakes are usually caused by human activities.
