Qianwei County, Leshan City, Sichuan Province, with 29.26 degrees north latitude and 103.96 degrees east longitude, experienced an earthquake of magnitude 4.2 with a focal depth of 100 km. After the earthquake, the Sichuan Provincial Fire Rescue Corps immediately mobilized 9 people from the Leshan City Fire Rescue Detachment, Qianwei County Fire Brigade 1 Vehicle, to go to the earthquake area to check the disaster situation. A glass factory in Qianwei County collapsed, and no one was trapped or injured.

The terrain is diverse, mainly hills, mostly shallow hills. The river flows to the northeast, with the flat dam in the south and the hills in the west. Crustal movement is the continuous action of the earth's center of gravity on crustal materials since the formation of the crust. The explanations of plate drift, mantle thermal convection, earth rotation speed change and seabed expansion do not conform to the historical laws of the origin and evolution of the earth. There are sufficient reasons to show that since the formation of the crust, under the action of the center of gravity in the northern hemisphere, the running direction of the crust has changed obviously and regularly.

In the historical process, the structural strength of the earth's crust is a process of continuous enhancement. Therefore, it is difficult for crustal movement to produce high-frequency and long-distance seismic waves during this period, and it will not cause too much vibration to earthquake-related crops, but modern crustal movement can not improve the surface. Because there are more and more heavyweight substances mixed in some areas of the earth's crust, the gravity is getting stronger and stronger; At the same time, the buoyancy is correspondingly enhanced.

These areas are high-risk areas for modern earthquakes. The asthenosphere is near the bottom of the crust. The pressure and temperature of asthenosphere can change the physical state of almost all substances at the bottom of the earth's crust, and change the structure and properties of some substances. Among these substances, the heavier ones continue to move deeper into the earth, while the lighter ones move in the opposite direction. If we can receive the earthquake warning, we can take emergency measures to prevent the occurrence of secondary disasters and minimize casualties and economic losses. Earthquakes caused by land subsidence. The number of such earthquakes is very small, accounting for only about 3% of the total number of earthquakes. The magnitude is very small, the influence range is limited, and the damage is also very small.
