摘　　要：整理2016年1月21日1时13分青海门源M_S 6.4地震数字化形变观测资料,分析此次地震同震响应记录,重点研究地倾斜同震响应随空间的变化特征。结果发现:地倾斜同震响应与地震台站位置有关,对于不同台站,同震响应具有不同的变化形态。统计认为,同震响应曲线形态具有的优势指向对发震断层走向具有一定指示意义。The digital deformation coseismic responding information caused by the earthquake occurred in Menyuan,Qinghai Province at1:30on January21,2016is concluded.There are four basic characteristics of coseismic response.In this paper,the crustal tilt coseismic response characteristics along with temporal-spatial distribution are mainly studied.The crustal tilt coseismic response is different with the different seismic stations.The statistics of coseismic response curves may have directional instructions for the seismogenic fault strike.
