A new tsunami forecasting method for near-field tsunami warning is presented. This method is applied in the German-Indonesian Tsunami Early Warning System, as part of the Indonesian Tsunami Warning Ce...
火山地层是由似层状、层状和块状结构组成的复合体,其地层结构的拟合是火山岩储层地震预测的难点所在,火山地层结构模型的建立是火山岩勘探开发中首先需要解决的关键问题.通过对九台和大屯典型火山岩地层结构的解剖,分析似层状结构和层状结构特征.似层状结构地层内部的岩层倾向和倾角变化大,与地层顶底面表现为斜交.从火山机构喷发中心到远端的同一方向的岩层具有同倾向、倾角逐渐变小的趋势,据此沿其顶面或底面的趋势进行内...
用面波方法研究上扬子克拉通壳幔速度结构
扬子克拉通 面波频散 地震各向异性 壳幔速度结构
2009/7/24
本文研究采用单台法和双台法提取了穿越上扬子的基阶面波相速度和群速度频散；通过对提取的面波群速度和相速度频散进行联合反演，得到的1-D SV速度模型显示上扬子块体下地壳S波速度与典型克拉通区域相当，其上地幔顶部80~170 km深处存在高速的岩石圈盖层，较AK135模型要快2%~3%，其岩石圈厚度约为180 km.在上扬子地区，径向各向异性集中分布在300 km以浅的岩石圈与软流圈部分，其中岩石圈部...
