China News Service, Beijing, May 28 (Guo Chaokai) At 2:4 on May 22, a magnitude 7.4 earthquake occurred in Maduo County, Guoluo Prefecture, Qinghai Province.

On the 28th, the Ministry of Emergency Management released the intensity map of the Mado 7.4 earthquake in Qinghai.

　　After the earthquake, the Ministry of Emergency Management and the Earthquake Field Work Team of China Earthquake Administration conducted investigations on the disaster area in accordance with the "Earthquake Field Work: Survey Specifications" (GB/T18208.3-2011) and the "China Earthquake Intensity Table" (GB/T17742-2020). An actual earthquake disaster investigation was carried out at 55 survey points, and the seismic intensity distribution of the earthquake was determined by referring to the scientific and technological support achievements such as the fault structure, the distribution of aftershocks, the focal mechanism, and the distribution of instrument intensity in the earthquake area, combined with the strong motion observation records, and the completion of the " The Qinghai Maduo M7.4 Earthquake Intensity Map was compiled, and the opinions of the Qinghai Provincial People’s Government, relevant state governments, and the Ministry of Housing and Urban-Rural Development have been solicited. It is now officially announced to the public.

　　The highest intensity of the Qinghai Maduo earthquake was Ⅹ (10 degrees). The macro-epicenter was located in Machali Town, Maduo County, and the micro-epicenter was located in Huanghe Township, Maduo County.

The area of ​​Ⅵ degree (6 degree) area and above is about 53704 square kilometers. The long axis of the intensity circle is northwest west, the long axis is about 381 kilometers, and the short axis is about 165 kilometers. It involves 3 cities, prefectures, 7 counties and 32 towns in Qinghai Province. , Sichuan Province, 1 city, prefecture, 1 county, 4 townships.

　　The X-degree (10-degree) area covers an area of ​​approximately 69 square kilometers, mainly involving Machali Town, Maduo County, Guoluo Tibetan Autonomous Prefecture, Qinghai Province.

　　The area of ​​Ⅸdegree (9 degree) area is about 1079 square kilometers, including anomalous area of ​​about 375 square kilometers, mainly involving Machali Town and Huanghe Township, Maduo County, Qinghai Province Guoluo Tibetan Autonomous Prefecture, Dawu Town, Maqin County, Youyun Township , Dawu Township.

　　The Ⅷ-degree (8-degree) district covers an area of ​​about 2,295 square kilometers, mainly involving Machali Town, Huanghe Township, Zhalinghu Township, and Huashixia Township, Maduo County, Guoluo Tibetan Autonomous Prefecture, Qinghai Province.

　　The Ⅶdegree (7 degree) district covers an area of ​​about 10,650 square kilometers, mainly involving Huanghe Township, Machali Town, Huashixia Town, Zhalinghu Township, Maduo County, Maduo County, Guoluo Tibetan Autonomous Prefecture, Qinghai Province, Dawu Township, Youyun Township, Maqin County, Dawu Township, Tehe Tuxiang, Dari County.

　　The Ⅵ degree (6 degree) district covers an area of ​​39,611 square kilometers, mainly involving Huanghe Township, Machali Town, Huashixia Town, Zhalinghu Township, Maduo County, Maduo County, Qinghai Province, and Xiadawu Township and Dongqinggou Township in Maqin County Township, Youyun Township, Xueshan Township, Dawu Town, Dawu Township, Dangluo Township, Lajia Town, Dari County Jimai Town, Sangrima Township, Jianshe Township, Tehetu Township, Wosai Township, Deang Township, Moba Township, Kequ Township, Jiangqian Township, Qingzhen Township, Shanggongma Township, Xiagongma Township, Ganglong Township, Gande County, Maduo Township, Chenduo County, Qumalai County, Yushu Tibetan Autonomous Prefecture, Zhaduo Township, Chengduo County , Qingshuihe Town, Balong Township, Gouli Township, Xiangjia Township, Zongjia Township, Dulan County, Haixi Mongolian and Tibetan Autonomous Prefecture, Changsha Gongma Township, Xiayi Township, Xinrong Township, Shiqu County, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, Yiniu Township.

　　In addition, Xiahongke Township, Shanghongke Township, and Manzhang Township, Dari County, Guoluo Tibetan Autonomous Prefecture, located outside the Ⅵ degree (6 degree) area, Xiazangke Township in Gande County, Zhiqin Township and Jiangjiang Township in Banma County Ritang Township, Yushu Tibetan Autonomous Prefecture, Yushu Tibetan Autonomous Prefecture, Qumalai County, Yuegai Township, Bagan Township, Yege Township, Qumahe Township, Qiuzhi Township, Chengduo County, Wenzhen Town and Xiewu Town. Hidden dangers of geological disasters have increased.

　　One of the outstanding features of this earthquake is the severe disaster and light casualties. The reason is that the earthquake fortification intensity in this area is eight degrees. After the implementation of poverty alleviation and the construction of settlements in agricultural and pastoral areas, the earthquake resistance has been significantly improved, so the proportion of collapsed houses in the collapsed damage is small. , Coupled with the low population density, greatly reduced casualties.

However, the damage to houses is still serious, especially the damage to infrastructure such as roads and bridges.

Experts reminded that if a large earthquake of a similar level occurs in a densely populated area, the casualties may be high. It is recommended that the implementation of reinforcement projects for housing facilities throughout the country be further increased to improve seismic fortification capabilities.

　　At present, emergency rescue and emergency transfer and resettlement in the disaster area have basically been completed, transportation, power, communications, and water supply have basically been restored, and the order of production and life is stable and normal.

The disaster area is more than 4,000 meters above sea level, the temperature is low at night, and there are aftershocks from time to time. The displaced people live in tents.

　　Experts suggest that the following key tasks should be done in the next step: First, the local party committee and government and relevant parties should continue to do a good job in mass resettlement, ensure the supply of living materials, and strengthen measures such as fire prevention, earthquake prevention, cold prevention, and epidemic prevention; second, further strengthen risks Hidden hazard investigation and prevention of secondary disasters; thirdly, speed up house safety identification and disaster loss assessment to lay the foundation for the start of restoration and reconstruction.
