Pennsylvania State University and its African partners operate and maintain the 53-station AfricaArray (AA) network for geophysical and meteorological observations. The AA fills a critical gap in the global seismic network and GPS networks. The AA seismic and GPS data are being used to improve assessments of seismic hazards and risks in seismically active regions of Africa. The AA's GPS and weather data fill in critical observation gaps in weather and climate observing systems for parts of Africa. The AA education and outreach activities bring opportunities for students at minority-serving institutions in the U.S. to participate in AA research and it provides training for undergraduate and graduate students, postdocs and technicians in Africa.This project funds Pennsylvania State University's continuing operation of the 53-station AfricaArray (AA). Each station is equipped with a combination of seismic, GPS and weather sensors. The AA addresses fundamental questions about the nature and evolution of continental rifting, cratons, hotspot volcanism, plateau uplift, and basin formation. The AA GPS data are greatly improving the ability to capture crustal movement caused by groundwater or soil moisture changes. The AA project sponsors underrepresented U.S. students and African undergraduate and graduate students, postdocs and technicians to study in a wide range of disciplines that benefit from AA observations.

宾夕法尼亚州立大学及其非洲伙伴运营和维护53个站点的非洲阵列（AA）网络，用于地球物理和气象观测。AA填补了全球地震台网和GPS台网的一个关键空白。AA地震和GPS数据正在用于改进对非洲地震活跃地区地震灾害和风险的评估。机管局的GPS和天气数据填补了非洲部分地区天气和气候观测系统的关键观测空白。AA的教育和推广活动为美国少数民族服务机构的学生提供了参与AA研究的机会，并为非洲的本科生、研究生、博士后和技术人员提供了培训。该项目为宾夕法尼亚州立大学53站非洲阵列（AA）的持续运行提供资金。每个观测站都配备了地震、GPS和气象传感器。AA解决了有关大陆裂谷、克拉通、热点火山作用、高原隆起和盆地形成的性质和演化的基本问题。AA GPS数据极大地提高了捕捉地下水或土壤湿度变化引起的地壳运动的能力。AA项目资助了一些代表性不足的美国学生和非洲本科生、研究生、博士后和技术人员，让他们从AA的观察中受益，在广泛的学科中学习。
