摘要
本文综述了1411年发生在西藏念青唐古拉山东南麓当雄8级地震及地震构造研究的概况;归纳了各家的研究论点,发现在以下几个方面存在着不同的结论:①念青唐古拉山东南麓断层的展布及结构特征;②地震形变带的若干结论;③1411年当雄8级地震的震级和震中位置。并认为有必要对上述问题进行进一步研究,以正确评估西藏拉萨-羊八井经济建设地区的地震危险性。
In this paper,a brief introduction to the earthquake (MS) occurring in 1411 at Dan- gxiong and on the southeast slope of the Nianqing Tanggula Mountain is made,and the study of its seismic tectonics are overviewed.It sums up the arguments of various schools and discovers some different conclusions in the following aspects:1.the features of the distribution and structure of faults on the southeast slope of the Nianqing Tanggula Moun- tain;2.several conclusions concerning the seismic deformation zone;3.magnitude and epicentral location of the 1411 Dangxiong earthquake (M8).It is also deemed nacessary to make further research on the above problems,so as to assess the seismic hazard correctly for the economic construction area in the Lhasa-Yangbajing region of Tibet.
