What are the causes of Ya 'an earthquake?

Earthquakes have always been a difficult problem in human prediction, prevention, rescue and post-disaster recovery. Let's talk about the cause of the earthquake.

Induced earthquake, an earthquake caused by external factors of a certain crust in a specific area, such as meteorite falling, reservoir water storage, deep well water injection, etc.

Tectonic earthquake is an earthquake caused by cracks, displacements and great changes in geological structures, so it is called tectonic earthquake, also known as fault earthquake.

Man-made earthquakes are earthquakes caused by human activities. Such as industrial blasting, underground nuclear explosion vibration; Deep wells and large reservoirs inject high-pressure water, which increases the crustal pressure and sometimes causes earthquakes.

Volcanic earthquakes are caused by a large number of hot magma ejected from the underground during volcanic eruption. The rapid expansion of volume impacts the earth's crust, leading to the rupture or dislocation of the earth's crust and local vibration, thus causing earthquakes.
