Why is Sichuan always so unlucky? Earthquake and debris flow ...

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 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 Longmenshan fault zone. Longmen Mountain is located at the eastern boundary of Bayan Kara Block, with Bayan Kara in the west and relatively hard Sichuan Basin in the southeast. The movement of Bayan Kara block was blocked by plate pushing, and faults were formed. Longmenshan fault has four large faults, with a total length of about 5 kilometers.

China, with 7% of the world's land, has 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 28 Wenchuan earthquake is still inconclusive.
