What should we think about the Zhouqu mudslide disaster? Please everyone, thank you.

The people of Zhouqu deserve sympathy ~ but there is also a thought-provoking side. The reason for the sudden outbreak of this mega mudslide has a few points. First, the 512 Wenchuan earthquake loosened the mountain, resulting in the internal structure of the mountain is not stable. Second, the meteorological aspect, due to drought led to the mountain cracks exposed, the soil is more brittle. The third is the washing away of heavy rainfall before the disaster. As for some people's claim that soil erosion may have been caused by indiscriminate logging. This is not valid. The reason is that the mountain over there is a mountain of earth, and there are no trees on it at all. So there is no talk of indiscriminate logging. Of course, the ZF is not without responsibility. Before the disaster, it should have taken into account the fact that the mountains are not solid, and Zhouqu is situated in a terrain where two mountains are sandwiched together, which makes it easy for disasters to occur when meeting torrential rains. ZF should do a good job of disaster warning, although not large trees, but can plant some other plants that can catch the soil, such as grass square and so on. There are also physical engineering aspects that can be done. So in this respect, the occurrence of this disaster is also a kind of wake-up call~
