AfricaArray (www.africaarray.org) is a long-term programme to build geosciences capacity in Africa in support of the mineral, petroleum, groundwater and environmental sectors. It seeks to do this by establishing effective Africa-based education and research programmes and observational networks, initially focused on geophysics, but planned to include other geoscience disciplines. The seismic network comprises 37 broadband stations in 16 countries as well as three temporary networks. More than 20 papers reporting on research findings have been published or are in press. Keywords: AfricaArray, Capacity building, Seismic network, Africa, Geosciences, Geophysics.
