摘要
2016年1月21日,青海省门源发生M_S6.4地震。这是继1986年8月26日青海门源M_S6.5地震30年后,在该地区发生的又一次震级相当的强地震。此次地震极灾区烈度为Ⅷ度,地震造成人员零死亡及较轻灾害损失。文章对该地震的基本参数、地震序列、地震背景、地震构造等作了概述,并对时隔30年发生在同一地区的两次强震做了对比分析。
On 21 Jan.2016,a MS6.4 earthquake occurred near by Menyuan,in Qinghai Province.It is an another disastrous earthquake taking place in Qinghai Province 30 years after the 26 Aug.1986 MS6.5 Menyuan earthquake.In the meizoseismal area,the intensity reachesⅧ.The earthquake disaster caused zero casualties and lighter losses.This paper summarizes the basic source parameters,earthquake sequences,seismological background and seismotectonic structures of this earthquake.The features of the two strong earthquakes occurred in the same area in 30 years was compared.
