From: Aborted propagation of the Ethiopian rift caused by linkage with the Kenyan rift
Evolution of rifting and current distribution of deformation in the Turkana depression. a, b Pliocene-recent schematic evolution of rifting. Coloured patterns in panel a delineate the main domains of tectonic and magmatic activity related to the Ethiopian and Kenyan rifts; the elliptical light orange pattern indicates the hypothesised extension of the region affected by deformation; black lines with arrows indicate the patterns of rift propagation15. Earthquakes are from the NEIC catalogue and focal mechanisms from the Global Centroid-Moment-Tensor (GCMT) Project64,65 (https://www.globalcmt.org). Dotted black line indicates the abandoned Ririba rift. c Sum of seismic moment release of earthquakes from the NEIC catalogue; superimposed are T-axes strike directions from the GCMT moment tensors (black lines). Dashed box indicates the region analysed by the temporary, local seismic networks deployed in northern Kenya28. Dotted dark grey line indicates the approximate location of the plate boundary deduced from models of geodetic data in East Africa12,29,30
