Why is Sichuan always so unlucky? Earthquakes and mudslides ...

Sichuan itself is a rainy area, and the snow and ice in the mountains will melt in summer, which provides enough water for the occurrence of mudslides. Secondly, Sichuan is mountainous and located in the earthquake zone, which leads to unstable earth and stone on the surface and is easily washed away by water.

Sichuan is an earthquake-prone area in China. For example, the Ya 'an earthquake occurred in the southern section of the Longmenshan fault zone. Longmen Mountain is located in the eastern border of Bayan Kara Block, with Bayan Kara in the west and relatively hard Sichuan Basin in the southeast. The movement of Bayankala block was blocked by plate nappe, and a fault was formed. Longmenshan fault has four large faults with a total length of about 500 kilometers.

China, which accounts for 7% of the world's land, suffered 33% of the world's mainland strong earthquakes, making it the country with the largest number of mainland strong earthquakes.

Whether the Ya 'an earthquake is the aftershock of the 2008 Wenchuan earthquake is still inconclusive.
