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，评估地壳不均匀程度，确定深部地壳组成的一级性质，并评估当地地震活动对岩石圈的应力。项目研究员将利用现有的沙特宽带地震数据获取阿拉伯地盾和红海部分地区的地壳和岩石圈结构图像。他们将联合收割机将沙特的地震数据与埃塞俄比亚的数据结合起来，包括最初部署25个台站，随后部署50个宽带台站。PI将分析地震活动性数据，以产生与计划中的红海北方MARGINS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.
