This project uses the Global Positioning System (GPS) to measure active deformation along the rift margins of the Red Sea. The project is being undertaken in cooperation with partner institutions in Egypt, Saudi Arabia, Eritrea, and Sudan. The ultimate objective of this research is to understand better the dynamics of continental rifting The approach includes both continuously recording GPS stations installed along the rift and survey GPS observations to determine variations in deformation style along and normal to the rift system. The GPS results are providing new constraints on the mechanics of continental rifting thereby adding to our understanding of the basic forces driving continental deformation and the rheological character of the continental lithosphere. In addition, this project is helping to transfer GPS technology to the host-country partners and is providing quantitative information on plate motions and rates of strain accumulation that are directly useful for evaluating and mitigating earthquake hazards.

该项目利用全球定位系统测量沿着红海裂谷边缘的活动变形。 该项目是与埃及、沙特阿拉伯、厄立特里亚和苏丹的伙伴机构合作开展的。本研究的最终目的是更好地了解大陆裂谷的动力学方法包括连续记录GPS站安装在沿着裂谷和调查GPS观测，以确定变形风格的变化沿着和垂直于裂谷系统。GPS结果为大陆裂陷力学提供了新的约束条件，从而加深了我们对驱动大陆变形的基本力量和大陆岩石圈流变学特征的认识。此外，该项目正在帮助向东道国合作伙伴转让全球定位系统技术，并提供关于板块运动和应变累积率的定量信息，这些信息对评估和减轻地震危害直接有用。
