According to historical earthquake data, an earthquake of magnitude 5.8 may occur in Xuanwei city, but the probability of occurrence is extremely small. According to the information released by the Seismological Bureau of Yunnan Province, at 08: 39 on October 27th, 2022, an earthquake of magnitude 3. 1 occurred in Xuanwei City, Qujing City, Yunnan Province (26.28 degrees north latitude, 104 degrees east longitude and10 degrees east longitude) with a focal depth of/kloc.

In addition, according to the official determination of China Seismological Network, an earthquake of magnitude 5.6 occurred in Xuanwei City, Qujing City, Yunnan Province, but the probability of occurrence is still small. There have been earthquakes in Xuanwei city in history, but the probability of occurrence is very small. Earthquake is a natural phenomenon, and its causes are complex and uncertain.

Causes of earthquake formation

1, plate movement of the earth: There are many plates on the earth, and there is a certain tension and pressure between them at any time. When this tension exceeds a certain level, the plates will shift and slide, leading to earthquakes.

2. Deformation and fracture of rocks: Besides plate movement, earthquakes may also be caused by deformation and fracture of rocks. Earthquakes also occur when the rocks in the earth bear too much pressure and deformation and the strata break.

3. Energy release inside the earth: There is a lot of thermal energy and geothermal energy inside the earth. When these energies are accumulated to a certain extent, they will be released outward, thus causing earthquakes.
