How much damage did Typhoon Hagupit (16) cause when it landed in Zhejiang?

Typhoon disaster is the most serious type of natural disaster that causes death in the world. It accounts for half of the deaths from natural disasters and seriously threatens the survival and development of mankind. The recent typhoon 16? Hagerby? Landing in Zhejiang. It has had a great impact on people's lives. The damage is as follows.

First of all, the strong atmospheric disturbance caused by typhoon will lead to the abnormal rise of sea level, which is easy to form a devastating storm surge disaster. The increase of water caused by typhoon and rainstorm will make the dike burst or overflow, thus forming flood; It will also cause seawater intrusion, soil salinization, fresh water pollution, agricultural production and water shortage. Moreover, in some coastal areas, the typhoon and storm surge seasons also coincide with the river signal period, which will cause more serious disasters. In addition, the rise of coastal sea level caused by global warming and land subsidence will not only increase the frequency and intensity of typhoon storm surge, increase the losses caused by typhoon storm surge disaster chain, but also reduce the urban drainage capacity.

Secondly, typhoon is a weather system with extremely low central pressure, with strong pressure gradient and extremely high wind speed. At sea, the maximum wind speed near the typhoon center can reach 100m/s, and on land, it can also bring strong winds. It can destroy houses and buildings, knock down trees and crops, destroy vehicles and other facilities, blow up cables, cause large-scale power outages, and may lead to fires and production accidents. Causing huge casualties and property losses.

Finally, it caused a rainstorm and brought disaster. In coastal lowlands, persistent typhoons and rainfall will cause large-scale flood disasters, inundate farmland, roads, wash away houses and river banks, and cause casualties and property losses. In coastal hilly areas, typhoons and rainfall may also cause large-scale collapse, landslides, mudslides, soil erosion and other geological disasters, causing huge losses to human life and property. In addition, in the process of rapid urbanization in coastal cities, human beings have over-exploited groundwater, and a large number of underground projects and high-rise buildings have caused land subsidence; Great changes in the nature of land use have reduced urban natural vegetation and river networks, and increased impervious areas such as roads, houses and factories. This will lead to the decline of urban drainage capacity and bring waterlogging disaster.
