Extended data
Wenchuan earthquake is a natural disaster. The plate movement caused the Wenchuan earthquake, which occurred in Longmen Mountain, that is to say, it occurred in the seismic belt under the joint action of Eurasia and Indian subcontinent, and there were three forces. There are several faults here: Longmenshan big breakpoint, Longmenshan back fault, Longmenshan main fault and Longmenshan marginal fault, which constitute the bane of this Wenchuan earthquake and 6,000 and 7,000 aftershocks.
As the southern plate of the Qinghai-Tibet Plateau continues to move southward, these substances flow downward, one to the southeast and the other to the east. Finally, the earthquake occurred in this part of the Longmenshan fault zone.
