  • 摘要: 2021年5月22日2时4分在青海省果洛藏族州玛多县境内发生MS7.4级地震,此次玛多MS7.4级地震是2008年汶川MS8.0级大地震之后中国震级最大的一次地震,及时查明其同震地表破裂展布及特征,对于正确认识发震构造和区域防震减灾具有重要意义。根据震后现场调查,结合高分辨率卫星遥感图像的解译分析、余震数据和典型地震地表破裂的无人机低空摄影测量等结果,初步获得了此次地震6处典型地震地表破裂的特征。结果发现:此次玛多地震的地表破裂主要沿已知的东昆仑断裂带的南侧分支断裂昆仑山口-江错断裂的东南段分布,分析表明其中的江错断裂应是此次地震的发震断层;同震破裂的西段总体走向275°~300°,主要表现为挤压鼓包和雁列式张裂隙的斜列组合,其中江错贡麻段至江多村段出现了明显的1.4~0.8 m的垂直位移,指示该段可能具有较明显的正断层成分;中部黄河乡段主要由一系列呈左阶斜列的北西向P剪切裂缝和右阶雁行排列的北东向张裂隙构成,走滑位移较小;而东段地表破裂出现了多个分支,其中北支昌马河段主要由一系列雁行排列的张裂隙组成,总体走向为260°,与断裂西段的走向明显不同;地震造成的最大左旋位移出现在西段的错尔加拉破裂段,约2.8 m,指示此次地震地表破裂带的走滑位移主要呈从西向东的单侧扩展-衰减特征。考虑到此次玛多地震出现在东昆仑主干断裂南侧的巴颜喀拉地块内部,表明该地块内部具有发生7级以上大地震的能力,因此,巴颜喀拉地块内部强震活动的孕震条件和机理应该是未来需要进一步关注的科学问题。
