Seismic and Geodetic Response to the 2007 Natron-Lengai Seismo-Magmatic Crisis, East African Rift, Tanzania

非洲大陆正沿着东非裂谷缓慢分裂。虽然界定这个裂谷的地貌很清楚，但裂谷的实际机制和岩浆活动在其中的作用尚不清楚。最近，一系列的低频地震（震颤）、活火山活动和地面变形表明，岩浆正在侵入东非裂谷的一部分。这为研究导致大陆分裂的过程提供了难得的机会。该提案是一笔用于探索性研究的小额赠款，用于增强现有的地震和GPS阵列，以收集数据，从而深入了解裂谷的性质和岩浆作用。更广泛的影响包括在坦桑尼亚开展国际合作和培训当地学生、培训研究生以及在一个发展中国家减轻灾害。

The African continent is slowly breaking up along the East African Rift. While the landforms that define this rift are clear, the actual mechanisms of rifting and the role of magmatism in this have been unclear. Recently, a series of low frequency earthquakes (tremor), active volcanism, and ground deformation, show that magma is intruding into one portion of the East African Rift. This allows for an unusual opportunity to study the processes that lead to continental breakup. This proposal is a Small Grant for Exploratory Research, to augment existing seismic and GPS arrays to collect data that will give insight into the nature of rifting and the role of magmatism in the process. Broader impacts include international collaboration and training of local students in Tanzania, training of graduate students, and hazard mitigation in a developing country.
