Geoscientists from across Africa, the United States, and Europe are building a pan-African initiative, AfricaArray, to strengthen geoscience education and research programs in Africa and to create an Africa-to-Africa academic support system. Universities, government agencies, and exploration companies are benefiting from the establishment of AfricaArray training programs coupled to a network of geophysical observatories spanning the continent. The observatory network provides support to the training programs and fosters community building by catalyzing collaborative projects and encouraging data sharing.
