Seismic Structure of the Crust and Upper Mantle in the Central and Northern Red Sea Focus Site

这项研究的主要目的是绘制红海的地壳和岩石圈几何图形，评估地壳的非均质性程度，确定地壳深部成分的一级性质，并根据当地地震活动评估岩石圈应力。PIS将利用沙特现有的宽带地震数据获取阿拉伯盾牌和红海部分地区的地壳和岩石圈结构的图像。他们将把沙特的地震数据与埃塞俄比亚的数据结合起来，这些数据包括最初部署的25个台站和后来部署的50个宽带台站。PIS将分析地震活动数据，以产生对红海北部计划进行的边缘地质/地球物理研究相关和有用的结果。

The main objectives of the study are to map the crustal and lithospheric geometries of the Red Sea, assess the level of crustal heterogeneity, determine the first-order nature of the deep crustal composition and evaluate lithospheric stress from the local seismicity. The PIs will use existing Saudi broadband seismic data to obtain images of the crustal and lithospheric structure of the Arabian shield and parts of the Red Sea. They will combine the Saudi seismic data with their Ethiopian data consisting of an initial deployment of 25 stations and a later deployment of 50 broadband stations. The PIs will analyze the seismicity data to produce results that would be relevant and useful to a planned MARGINS geological/geophysical study of the northern Red Sea.
