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.

非洲大陆正沿着东非大裂谷慢慢分裂。 虽然定义这条裂谷的地形很清楚，但裂谷的实际机制和岩浆活动在其中的作用却尚不清楚。 最近，一系列低频地震（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一个不寻常的机会。 该提案是一项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，从而深入了解裂谷作用的性质和岩浆活动在这一过程中的作用。 更广泛的影响包括国际合作和坦桑尼亚当地学生的培训、研究生的培训以及发展中国家的减灾。
