摘要
近十多年来中国内地强震主要围绕青藏高原内部块体边界发育,如2008年汶川8.1级地震、2010玉树7.1级地震、2021年玛多7.4级地震、2022年门源6.9级地震等。其中青海省位于青藏高原东北部,块体构造复杂,变形强烈,自2010年以来6.0级及以上地震共计发生8次,占中国内地6.0级及以上地震约22%,为地震频发区。本文基于地震现场资料、应急管理部、中国地震台网中心、美国地质勘探局(USGS)等不同信息源,对2010年以来青海6.0级及以上地震灾害情况进行汇总,并对主要震例震害特征及其抗震设防特点进行分析讨论,为后续青海地区震害防御提供相关建议。
In the past decade,strong earthquakes in China'mainland have mainly developed around the boundary of the Tibetan Plateau,including Wenchuan 8.1 earthquake in 2008,Yushu 7.1 earthquake in 2010,Maduo 7.4 earthquake in 2021,Menyuan 6.9 earthquake in 2022,etc.Qinghai province is located in the northeast of the Qinghai-Tibet plateau,with complex block structure and strong deformation.Since 2010,a total of 8 earthquakes with magnitude 6.0 or above occurred,accounting for about 22%of the earthquakes of magnitude 6 or above in China'mainland.In this paper,we collected the earthquake data from field investigation,as well as from the Ministry of Emergency Management,the China Earthquake Networks Center,the United States Geological Survey and other different information sources,summarized the earthquake hazards of earthquakes with magnitude 6.0 or above since 2010 in Qinghai region,and analyzed the characteristics of major earthquake damage and seismic fortification to provide relevant suggestions for seismic disaster prevention in Qinghai in the future.
