Durheim 3 1: Royal Museum for Central Africa, Tervuren, Belgium 2: Pennsylvania State University, Pennstate, USA 3: University of the Witwatersrand, Johannesburg, South Africa 2017 EPOS Seismology Workshop, ORFEUS Annual Workshop, EMSC General Assembly

  3. AfricaArray Background • Started in 2004 - founding partners: Penn State, Univ. of the Witwatersrand (Wits), Council for Geoscience (aka Geol. Survey of South Africa (CGS) (+ IRIS support) • Initial meeting with Paul Dirks – Oct. 2003 • Dec. 2003 AfricaArray: Training a Scientific Workforce for Africa’s Natural Resource Sector (This is a concept paper written to gauge the level of interest on the part of funding agencies for establishing a public-private partnership to support this initiative. ) Andrew A. Nyblade, Department of Geosciences and the Alliance for Earth Sciences, Engineering and Development in Africa (AESEDA), Pennsylvania State University, University Park, PA 16802, USA email: andy@geosc.psu.edu Summary Highly trained scientists in fields allied to natural resource exploitation are needed in government, industry and academic institutions throughout Africa who are dedicated to building the African scientific community, and who can play pivotal roles in the development and management of Africa’s vast mineral and petroleum wealth, and water and geothermal resources. AfricaArray will address the limited capacity in the relevant science fields by establishing a

  4. AfricaArray Background • Goal: establish a public-private partnership to support capacity building and research in the geosciences (Earth, Atmospheric and Space sciences) in Africa, with and initial focus on solid earth geophysics • “AfricaArray” = array of training programs + array of research projects + array of partnerships and collaborations + array of scientific observatories (networks) • Key components to a multifaceted initiative: 1) seismic, GPS, weather networks in Africa 2) Undergraduate and postgraduate research and education programs (Africa and US) 3) Project based funding

  5. Progress • Funding: – Supported by a public-private funding partnership; major contributors – NSF, NRF, Wits, Penn State, Council for Geoscience, corporate sponsors • Education: – completed: > 72 BSc honours, 22 M.S., 13 Ph.D., 13 Postdocs; – current: Wits: 5 BSc honours, 15 M.S., 10 Ph.D., 3 Postdocs – current: PSU: 2 M.S., 1 Ph.D. • Networks: – 53 permanent seismic stations in 17 countries – several temporary seismic networks • Partners: – Universities in Africa 15 – Universities in US, Europe, Australia 14 – Gov ’ t organizations in Africa 17 – Gov ’ t organizations outside Africa 8 – companies 19 – Academic and industry societies 6 • Science output: – Many projects completed; > 70 papers in refereed journals

  6. AfricaArray Observatory Network • 53 stations • 50 seismic stations • 24 GPS/met stations • 17 countries • Continuous recording • Data recovery 70-80% • Data availability: IRIS and UNAVCO • Data retrieval: – A few countries - real- AfricaArray Observatories (January 2016; 51 total) time using cell modems – Elsewhere - monthly collocated seismic, GPS, weather 20 collocated seismic, GPS 1 collocated GPS, weather 2 1 GPS only 0 1000 2000 3000 seismic only 29 elevation (m)
