Abstract:

青藏高原是我国现代构造活动和地震活动最强烈的地区,自有地震记录以来,在高原内记录到多达18次8级以上巨大地震和100余次7~7.9级地震,它们均发生在喜马拉雅板块边界构造带和板内断块区及其次级断块的边界活动构造带上.自1900年有地震仪器记录以来,青藏高原曾经历了3次地震活动丛集高潮,即1920-1937年,1947-1976年和1995-现在.在每次地震活动丛集期都形成以8级地震为核心的7级以上地震活动系列,它们分别是20世纪20-30年代的海原-古浪地震系列、50-70年代察隅-当雄地震系列和20世纪末期以来昆仑-汶川地震系列.每一个地震系列都有自己的主体活动区,最新的昆仑-汶川地震系列的主体活动区为巴颜喀喇断块.青藏高原地震活动高潮与全球Mw≥8.0巨大地震活动高潮紧密相关,昆仑-汶川地震系列与自2001年至今的全球最新地震活动高潮相对应,它们反映了两者的动力学联系.经过详细对比研究认为,它们至今均仍在延续之中,全球板块边界构造带8~9级地震和板内大陆断块区的7~8级地震都仍在连续发生.研究了全球和区域地震活动的相关关系及青藏高原地震活动的时空分布特征,指出了该区当前地震活动的总体形势,评价了其近期地震危险性,提出了加强地震监测的建议.
