【摘要】 基于上海地震台阵记录的远震利用台阵处理技术研究了PpSmS、P660S及SKS震相的分裂。根据三震相的分裂参数(快慢波延时时间及快波偏振方向)的差异对上海地震台阵地区地壳、上地幔及下地幔介质的各向异性情况进行了简要分析。更多还原

【Abstract】 Based on the teleseismic events which were recorded by shanghai seismic array and using seismic array process technology, the split of PpSmS,P660S and SKS phases are studied. The split parameters of PpSms,P660S and SKS are calculated ,the mantle and crust medium anisotropies under shanghai seismic array region are analyzed briefly according to the difference among PpSmS, P660S and SKS split parameters.更多还原
