Tectonic setting of the Turkana depression. a Quaternary faults, seismicity and Quaternary volcanoes in the Turkana depression and surrounding regions superimposed on a SRTM (NASA Shuttle Radar Topography Mission) digital elevation model (modified from ref. 17). Seismicity from USGS National Earthquake Information Center (NEIC) catalogue (https://earthquake.usgs.gov/earthquakes/search/); Quaternary volcanoes from the Smithsonian Institution, Global Volcanism Program62 (http://volcano.si.edu/). Red lines delineate the deformation domains of the Kenyan rift, Kino Sogo fault belt (KS)-Gofa Province, and Main Ethiopian rift13, 15. Black square indicates the area illustrated in Fig. 2. CB: Chew Bahir basin; D: Dilo-Dukana volcanic field; HH: Hurri Hills; LI: Lokitipi basin; LT: Lake Turkana; LR: Lokichar basin; M: Mega volcanic field; MV: Marsabit volcano; SB: Segen basin; RR: Ririba rift. b Location of the East African rift (white lines); c schematic fault pattern and present-day plate kinematics. Black arrows show relative motions with respect to a stable Nubian reference frame according to the best-fit model of ref. 12. Values besides arrows indicate motion in mm per year. White square indicates the area portrayed in panel a. NU: Nubian plate; SO: Somalian plate; VI: Victoria microplate
