How to deal with mudslide disasters.
What is a mudslide? What is a geohazard?
On August 7, Zhouqu County, Gansu Province, suddenly fell heavy rain, and then a mudslide poured down in the early morning of the 8th. The sudden flash flood has killed 1,435 people and left 330 missing. Why does a rainstorm cause such a strong mudslide?
What exactly is a mudslide?
Debris flow refers to a special torrent that exists in mountain ravines and is triggered by water sources such as heavy rainfall, water and snow melt, and contains a large amount of sediment and stones. Mudslides generally occur during the rainy summer and autumn seasons, during the peak of a single rainfall period, or after a continuous rainfall occurrence. In addition, it is necessary to have abundant loose materials and to be able to match the steep terrain and landforms where the above loose materials are concentrated with water sources.
In addition, unreasonable human economic activities can also induce mudslides. When debris flow occurs, it will cause the dual effects of geological disasters such as collapse and landslide and flood damage, and its harm degree is more extensive and serious than that of a single collapse, landslide and flood.
Mudslides are just one type of geological disaster. Geological disasters refer to geological processes (phenomena) formed under the action of natural or man-made factors that cause damage and loss to human life, property and the environment, such as collapses, landslides, debris flows, etc. According to the statistics of the Ministry of Land and Resources, as of July this year, compared with the same period last year, the number of geological disasters in China, the number of deaths and disappearances and direct economic losses have increased significantly, of which landslides account for the largest proportion of geological disasters.
Debris flows often occur with heavy rains and floods, and in the season when debris flows are common, we should listen to the meteorological forecast of geological disasters in time and take preventive measures.
