How do faults generate earthquakes?

You can think of mini version bugs like board border. The fault is a crack of the Earth's crust, the upper layer of the rock around the Earth. The crust floats above the mantle, which is the lava that constitutes the bulk of the interior of the earth.

By contrast, the plate is one of the huge rocks that make up the Earth's crust, and the plate boundary is the place where the plates encounter and interact.

Essentially the same stresses in the Earth's crust that cause the formation of faults will also create pressure on it.

You must remember that we deal with rocks in the basement - the mistakes are not smooth and unified

This movement is slow and it is not enough for us to feel something - it has accumulated for hundreds of years. But as rocks pass each other's rock it can be caught - stuck on another rock

Earthquakes in the fault - Lateral deflection earthquakes occur in horizontal faults, normal earthquakes occur in normal faults, thrust type earthquakes occur in thrust faults. When an earthquake occurs in one fault, the rock on one side of the fault slips against the other side. The fault plane can be vertical, horizontal, or oblique to the surface of the earth. Slide direction can be any angle

What is the relationship between the fault and the earthquake? What happens when an earthquake occurs?

Sometimes, a so-called earthquake storm produces a series of earthquakes occurring in the earthquake Each earthquake is caused by vibration and stress redistribution of the previous earthquake. These are similar to aftershocks, but in adjacent fault segments these storms have occurred over many years and some of the subsequent earthquakes are as destructive as the initial earthquakes. This model was observed in a series of 12 earthquakes occurred in the Anatolian Fault in the northern part of Turkey in the 20th century and an old and abnormally large earthquake group was estimated in the Middle East.

Whenever an earthquake hits a cluster, a series of earthquakes occurs in various storms of earthquakes. The tsunami is a dangerous form of earthquake in which a series of sudden changes occur in the ocean due to strong earthquakes. It is a very serious problem for people's lives, security, seismic engineering, including swallowing coastal areas, sweeping out the whole town and destroying houses. Unfortunately there is no way to stop people from running away from people and warning them to save lives through various warning systems.

In the most general sense, the term earthquake is used to denote any earthquake event that generates seismic waves, whether natural or human. Earthquakes are mainly caused by destruction of geological faults or other events such as volcanic activity, landslides, mine explosions, nuclear tests and so on. The first failure point of the earthquake is called epicenter or epicenter. The epicenter is at the base point just above the source. Tectonic earthquakes occur everywhere on the earth where there is sufficient accumulation of elastic strain energy to move the crack along the fault plane. Only when the frictional resistance increases along the surface of the fault without irregularity or roughness the side of the fault can move smoothly and without vibration. Most fault planes have such roughness, which leads to stick-slip behavior.
