摘　　要：本文整理统计了2023年中国5.0级(含)以上地震目录,归纳2023年度中国大陆地震灾情信息。结合有关省(自治区、直辖市)地震局的地震灾害评估报告等资料,列举典型震例的灾害损失结果和地震灾害特点。通过综合对比近20年来中国大陆地区历史地震灾情数据,分析灾害性地震发震频次和地震伤亡人数的年际变化得出,2023年中国地震灾害损失较重且较为集中,房屋损坏、人员避险不当以及次生地质灾害是造成人员伤亡的主要原因。This study summarizes earthquake disaster information and key characteristics in Chinese mainland by compiling a catalog of earthquakes with magnitudes of 5.-0 or greater in 2023.Drawing on earthquake disaster assessment reports from provincial seismological bureaus,data on disaster losses,and analyses of typical earthquake cases,the main features of earthquake-related impacts are identified.By comparing historical earthquake disaster data from the past 20 years and examining inter annual variations in earthquake frequency and casualty numbers,it is concluded that earthquake-related losses in China in 2023 were both heavier and more concentrated.The primary causes of casualties were housing damage,inadequate evacuation measures,and secondary geological hazards.
