According to the survey released by China Seismological Station, an earthquake of magnitude 3. 1 occurred in Ludian County, Zhaotong City, Yunnan Province on August 2 17: 49, with a focal depth of 10 km. After the earthquake disaster, many workers engaged in earthquake disasters, disasters, natural environment and structures will invest a lot of money and care. In addition, properly distributing the daily life of the people in the disaster areas is also the key work of today's rescue and disaster relief.

Yunnan Province is located in the northwest of Indian Ocean Plate and Eurasian Plate, where the two plates collided and squeezed, resulting in Sichuan Basin. At present, this geological fitness movement is still in progress, and the surface is constantly changing, so earthquakes will occur every once in a while, releasing the ground stress transformed by the surface. China is a country with a vast territory and frequent earthquakes, with eight major earthquake-stricken areas and dozens of minor earthquake fault zones. The areas with more earthquakes in China include China, Taiwan Province, Xizang Autonomous Region, Yunnan, Qinghai and Sichuan. The earth's atmosphere is covered by plates of different sizes, which are separated from each other or squeezed with the fluid core driving force directly below them. Most earthquake disasters occur in bright red wire frames at the junction of plates.

About 50 million years ago, the Indian plate hit the Eurasian plate northward, and the huge impact caused the Yunnan-Guizhou Plateau and the Himalayas to uplift. This vicious collision continues. The satellite navigation system shows that the Indian plate is still advancing northward at a speed of 5cm, which is equivalent to the growth and development of nails. Yunnan-Guizhou Plateau suffers from intense compressive energy. Moving north and northeast, the crimson arrow symbol indicates the moving direction, and the length indicates the moving distance.

When the Yunnan-Guizhou Plateau moved eastward, it met the Sichuan Basin with a long history, and the extrusion energy was dispersed to Yunnan Province in the south. Sichuan-Yunnan region has become one of the regions with the most earthquake disasters in China. Regional destructive earthquakes in Yunnan province, especially earthquake disasters with magnitude of 6 or above, are not everywhere. The key earthquake disasters in the world are concentrated in three major earthquake fault zones, namely, the Pacific Rim earthquake fault zone, the Eurasian earthquake fault zone and the Hailing earthquake fault zone.
