What are the natural disasters in China?

First, the earthquake activity is frequent, and the Ludian earthquake caused serious casualties. In the first three quarters, there were 5 earthquakes 15 in Chinese mainland, including 6 in Yunnan and Xinjiang and 3 in Tibet. There were three earthquakes of magnitude 6 or above, namely1February Yutian earthquake of magnitude 7.3 in Xinjiang, May 30th Yingjiang earthquake of magnitude 6. 1 in Yunnan, and August 3rd Ludian earthquake of magnitude 6.5. Among them, the Ludian earthquake with Ms 6.5 in Yunnan is the strongest earthquake in Ludian area with historical records, and it is also the strongest earthquake after the Yao 'an earthquake with Ms 6.5 in Yunnan Province in 2000, resulting in 6 17 deaths,12 missing, 3 143 injured and more than 200,000 farmhouses. It has seriously affected the production and life of the local people, resulting in direct economic losses of 2 billion/kloc-0.40 billion yuan (including Yunnan/kloc-0.985 billion yuan, Sichuan/kloc-0.70 billion yuan and Guizhou/kloc-0.20 billion yuan). Compared with the same period since 2004, the losses caused by earthquake disasters are obviously more, and the number of deaths and missing persons due to disasters is second only to 20 10 of Wenchuan earthquake in 2008 and Yushu earthquake in Qinghai.

Second, the flood disaster is generally light, and some areas in the south are seriously affected. In the first three quarters, more than 50 rivers in China experienced floods exceeding the guaranteed water level, more than 20 rivers experienced floods exceeding historical records, and the southern region suffered 33 large-scale heavy rainfall. In the middle reaches of the Yangtze River, Yuanjiang, the Dongting Lake system, was flooded with the highest water level in history, and Beijiang, the Pearl River basin, was flooded once every 10 years, causing waterlogging in many urban areas, which greatly affected people's production, life and transportation. According to statistics, in the first three quarters, floods (including geological disasters) caused 7704 18 counties (cities, districts) in 28 provinces across the country to be affected, 7 12 people died and disappeared, and 3.666 million people were resettled urgently. 249,000 houses collapsed, and 6.5438+0.3 million houses were damaged to varying degrees; The affected area of crops is 5 139.4 thousand hectares, of which 753.6 thousand hectares will not be harvested. Compared with the same period since 2004, flood disasters (including geological disasters) are generally light, and the number of people missing due to disasters, the area affected by crops, the area where crops were not harvested, and the number of damaged houses are all about 50% less. Among them, Jiangxi, Hunan, Guangdong, Guangxi, Chongqing, Sichuan, Guizhou, Yunnan and other places were seriously affected, and the number of missing persons, emergency resettlement population and damaged houses accounted for more than 70% of the total losses in the country.

Third, there is high temperature and little rain in the northern region, and summer drought is prominent in Huanghuai and other places in the northeast. Since July, the high temperature and lack of rain in Northeast China, Huanghuai and other places have led to the rapid development of drought, reaching a peak in early August and gradually easing in late August, but it still has a certain impact on autumn grain production in some areas. According to statistics, drought * * * caused 1 province (autonomous region) 7 10000 people to be affected, and 1000 people needed life assistance due to drought. The affected area of crops is more than 8,000 thousand hectares, of which no crops are harvested 1000 thousand hectares. Compared with the same period since 2004, the drought is generally light, and the affected area, crop failure area and direct economic loss of crops are less than 30%. Among them, Hebei, Inner Mongolia, Liaoning, Jilin, Henan, Hubei, Shaanxi, Ningxia and other provinces were seriously affected, and 9.755 million people were rescued due to drought; The affected area of crops is 7028 thousand hectares, of which 9710.9 thousand hectares will not be harvested.

Fourth, the number and frequency of typhoon landings are relatively small, and the history of super typhoon is rare. In the first three quarters, five typhoons landed in Chinese mainland, and the number of landings was obviously less than that in the same period of the previous year (6.5). Among them, it is rare that there was no typhoon in August. Generally speaking, typhoons landed in China earlier this year, among which 1409 typhoon rammasun and 14 16 typhoon Medham landed three times respectively, and 14 16 typhoon landed as many as four times, which was the first time in 25 years. "rammasun" is the strongest typhoon that landed in South China since 1973, and it also has the most serious impact on Hainan Province since 2000. More than 0/00 flights in Hainan and other places were cancelled, many ferries and passenger ships were suspended, and many trains were suspended. Haikou and Wenchang in Hainan, Xuwen and Leizhou in Guangdong, Beihai and Fangchenggang in Guangxi were once interrupted in large areas, and seawater backflow occurred in many places. According to statistics, in the first three quarters, typhoon disaster * * * caused11364 counties (cities, districts), 26 150000 people died and disappeared,17/kloc-. 53,000 houses collapsed and 590,000 houses were damaged to varying degrees.

Fifth, the low temperature rain and snow affected Spring Festival travel rush at the beginning of the year, and the loss of wind and hail disasters was relatively light. In February, frequent low-temperature rain and snow weather processes continued to occur in the central and eastern regions, and the maximum cooling range was generally above 18 degrees, and the cooling range in some areas reached 18 degrees. Low-temperature freezing and snowstorm occurred in Anhui, Zhejiang and Hubei, causing 10 deaths, freezing cash crops such as tea and rape, and damaging some power and communication infrastructure. Among them, the large-scale rain and snow weather process in central and eastern China on February 4-7 had a great impact on the return traffic in Spring Festival travel rush. According to statistics, in the first three quarters, 22.597 million people in 30 provinces 1 132 counties (cities, districts) were affected, 165 people died and disappeared, and1/0000 people were urgently relocated. 65,438+2,000 houses collapsed and 288,000 houses were damaged to varying degrees. Compared with the same period since 2004, the disaster situation is generally light, with less than 50% missing persons, emergency resettlement population and damaged houses.
