Our earth, its shell is actually equivalent to the thickness of a piece of paper. Compared with the large volume of the whole earth, its thickness is very thin, so the crust is squeezed during the movement and then breaks. This earthquake is an important reason for the formation of this fault zone. Earthquakes are actually collisions and compressions between plates, and then the plate edges and plates move, which will lead to a greater degree of rupture of the already fragile crust.
Qinghai earthquake is a tectonic earthquake. Our earth is constantly moving, its internal materials are also constantly moving, and the crust is also constantly evolving, which makes different geological structures change and leads to changes in the surface crust. This fault structure has great influence on building engineering.
However, the fracture zone is of great significance to surface investigation and hydrogeological research. When the geological fault is thousands or even hundreds of kilometers deep, it is called deep fault. If it appears in batches, it will form a larger fault zone, giving people the opportunity to discover water, oil and gas. At that time, when the Sichuan and Yushu earthquakes occurred, very large fault zones could be seen everywhere on the ground. If people are not careful, they will fall down. Many oil fields and atmospheric production sites were discovered in this way. I hope this earthquake can also find new phenomena.
