The article first appeared in the challenge of Jishi Mountain**, which affected Jintian Village, Zhongchuan Township, Haidong City, Qinghai Province. A landslide not far from Jintian Village was triggered, causing a large amount of mud to flow into the village suddenly in the ditch, causing more than a dozen villagers to be washed away by the mud and buried until they lost contact. The highest amount of sediment is about 10 meters, and many people's houses have been filled with sediment, filling in, and more than 100 people have been injured, making it difficult to search and rescue the missing villagers, and they are still being searched and rescued
A large amount of sediment washed up at the entrance of the village.
Houses flooded with sediment.
After watching the introduction of CCTV engineers, I knew: the scientific name of sediment in this autumn and winter".Sand surge"Also called".Underground gushing”。There is a difference between a sand surge and a mudslide.
The "mudslide" is mainly triggered by rainfall, melting ice and snow and other water sources, and mainly occurs in spring and summer.
Sand surges are mainly composed of liquefied sand, while debris flows contain a mixture of soil, stones, trees, etc。Sand swells mostly occur in areas with abundant water-bearing sandy layers, such as deserts. Mudslides are mostly found in mountainous and hilly areas.
Tree branches, sediment, and all kinds of debris in the mudslide.
Because Jintian Village in Qinghai is about five kilometers away from Jishi Mountain, Jishi Mountain** caused a sand gushing out of a river ditch leading to Jintian Village, which rushed directly to Jintian Village along with the road. It is said that the mud and sand waves are as high as a meter, and it is scary to think about, and if I were at the scene, I would be stupid directly!
Sand surge"Another new term was born. Every time a disaster occurs, a new word is created, but it is synonymous with disaster. If we want to make this synonym for disaster disappear, we need to encourage everyone to take care of the environment, grow more trees, prevent desertification of the land, and truly turn the desert into an oasisSand surge"This geological disaster has become history, we must take care of wild animals and let nature return to nature, so that we can reduce some natural and man-made disasters.
