(a) Temporary seismic stations deployed in Ethiopia plotted on SRTM digital elevation model. Grey circles are from the Ethiopia Afar Geoscientific Lithospheric Experiment (EAGLE) during October 2001–February 2003. White squares are from the Boina Broadband Network operational during October 2005–September 2006. Grey triangles are 'SEARIFT' seismic stations operating during March 2007–October 2009. White stars are 'Afar Consortium' seismic stations deployed during October 2007–October 2009. BOOE and ALEE are seismic stations Boina and Ado'Ale, respectively, deployed in the Dabbahu magmatic segment (D). Solid black lines are Oligo-Miocene age border faults. Solid red shapes are Quaternary-Recent magmatic segments. The Main Ethiopian rift (MER), Red Sea rift (RSR) and Gulf of Aden (GA) rift form the three arms of the Afar Triple Junction. Dashed-red lines show zones of submarine seafloor spreading. The MER terminates at the Tendaho-Goba'ad Discontinuity (TGD), shown by a black dashed line. (b) Distribution of local seismicity recorded during the operation of the named temporary seismic stations. Motions of the Arabian and Somalian plates relative to a fixed Nubian plate are shown as grey arrows.
