【摘要】 基于2014年于田M_s7.3级地震周边地区的GPS连续观测站数据,得到了此次地震的近场地表运动和同震位移,分析了此次地震的地壳形变特征。结果表明,此次地震引起的地表运动显著,GPS记录到的最大位移振幅远超过最终的同震位移,其中距离展中约印如m的XJYT站记录到了西向74.7mm和北向39.9mm的最大位移振幅,同震位移为西向20.0mm和北向9.8mm。2008年于田M_s7.3级地震在一定程度上触发了此次地震。更多还原

【Abstract】 The ground motion and coseismic deformation of 2014 Yutian M_s7.3 earthquake are acquired by processing the data from continuous GPS stations around the earthquake.The result shows that the ground motion was remarkable.The maximum displacement amplitude recorded by GPS is greater than the coseismic deformation which is observed in limited region.The maximum displacement at XJYT station,which is 60 km away from the epicenter,is about 74.7 mm westward and 39.9 mm northward.The coseismic deformation at XJYT on the other hand,is about 20.0 mm westward and 9.8 mm northward.This earthquake may be trigged by the 2008 Yutian M_s 7.3earthquake in some degree.更多还原
