20 12 disaster that has happened!
It was approved that in the first half of 20 12,1133610000 people were affected by various natural disasters, 465 people were killed, 97 people were missing, and1kloc-0/5.04 million people needed emergency assistance. The affected area of crops 1 1732.8 thousand hectares, of which 988.5 thousand hectares were rejected; 186,000 houses collapsed, 378,000 houses were seriously damaged, and 808,000 houses were generally damaged; The direct economic loss was 77.38 billion yuan (excluding data from Hong Kong, Macao and Taiwan).
In the first half of the year, floods (including landslides and mudslides), wind and hail were the main natural disasters in China, and droughts, earthquakes, low-temperature freezing, snowstorms and typhoons also occurred to varying degrees, and the disasters were lighter than those in the same period in recent years. Mainly presents the following characteristics:
First, hail and floods are the main disasters, and the overall loss is light. In the first half of the year, the number of people who died or disappeared due to hail and flood disasters accounted for 92% of the total number of people who died or disappeared due to disasters, and the number of people who were damaged by houses accounted for more than 70% of the total number; Compared with the same period since 2002, the loss of natural disasters is generally light, and other indicators are lower than the average of the same period in recent years except for direct economic losses.
Second, repeated disasters were serious, and losses were concentrated in the central and western regions. In the first half of the year, more than 10,000 counties (autonomous regions and municipalities) in China were affected to varying degrees, more than 60% were affected more than twice and nearly 40% were affected more than three times. Seven provinces (autonomous regions) of Jiangxi, Hunan, Guangxi, Sichuan, Yunnan, Gansu and Xinjiang account for nearly 70% of the national total, and indicators such as emergency relocation, damaged houses and direct economic losses account for more than 50% of the total. Third, the casualties of mountain torrents are outstanding, and local disasters are abnormal. Heavy rainfall caused flash floods, landslides and mudslides in some hilly areas, causing serious casualties, especially in Min County, Gansu Province and ningnan county, Sichuan Province, which caused a large number of deaths and disappearances; From April to June, there were 18 rainstorms in southern China, and parts of Jiangnan and southern China continued to suffer. The flood season in Inner Mongolia is ahead of schedule, and the rainfall in many places has exceeded the historical extreme value, and crops have been affected in a large area with obvious losses.
Fourth, the regional drought is remarkable, and the low temperature of snow disaster in the west is prominent. Yunnan and southern Sichuan suffered severe drought in winter and spring for the third consecutive year, and spring drought occurred in parts of North China, Northeast China and eastern Inner Mongolia. Due to the continuous high temperature and lack of rain, the drought in some areas of Huang-Huai-Hai has developed rapidly (since the flood season, the drought in most parts of the country has been effectively alleviated except some areas of Huang-Huai-Hai); In the first half of the year, some areas in the west suffered from severe snowstorms and low-temperature freezing injuries, and * * * caused 12 1 county (area, city) and 44 regiments of the Corps to be affected, accounting for more than 70% of the counties affected by low-temperature snowstorms in China.
Fifth, there are many wind and hail spots, and the influence of dust is late. The average number of strong convective days in China is 15. 1 day, the highest since 2007. Except for 30 overseas provinces (autonomous regions and municipalities directly under the Central Government) and Xinjiang Production and Construction Corps, they all suffered from wind and hail disasters to varying degrees, and 94/kloc-0 counties (autonomous regions, cities and banners) were affected, accounting for nearly one-third of the total number of counties in China. The first sandstorm happened later than the last ten years 1 many months, which is the latest year since 200 1. Sandstorm disasters caused the collapse of a large number of vegetable greenhouses in Inner Mongolia, Tibet, Gansu, Qinghai and Xinjiang, which had a great impact on agricultural production.
Sixth, typhoon losses are slight, and moderate and strong earthquakes are concentrated in the west. China has been affected by two tropical cyclones "Teli" and "Du Surui" successively, and the initial landing time of "Du Surui" is close to the same period of the year, causing slight losses; There were 10 earthquakes with magnitude above 5 in Chinese mainland, all in the western region. Among them, moderate earthquakes in Xinjiang continued to be active, with 7 earthquakes of magnitude 5 or above occurring in * *, with the highest magnitude of 6.6 at the junction of xinyuan county and Jingxian County on June 30th.
And the recent 7.3-magnitude earthquake in Japan.
