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慢慢解体。虽然定义这一裂谷的地貌很清楚，但裂谷的实际机制以及岩浆作用在其中的作用一直不清楚。最近，一系列低频地震(震颤)、活火山作用和地面变形表明，岩浆正在侵入东非裂谷的一部分。这为研究导致大陆解体的过程提供了一个不同寻常的机会。这项提议是探索性研究的一小笔赠款，旨在增强现有的地震和GPS阵列，以收集数据，深入了解裂谷作用的性质和岩浆作用在这一过程中的作用。更广泛的影响包括坦桑尼亚当地学生的国际合作和培训、研究生培训以及发展中国家的减灾。

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.
