a Magmatic segments (red shading), faults (black lines), and Quaternary volcanoes (yellow triangles)68. The red dots mark earthquakes in CA from the International Seismological Center (ISC) catalog69,70 and ref. 34. (Supplementary Data 1). RS Red Sea Rift, GA Gulf of Aden Rift, MER Main Ethiopian Rift, DMH Dabbahu-Manda-Harraro, AG Assal-Goubbeth. b, c Average LOS velocities (vel.) from ascending 014 and descending 006 orbits, respectively. The black arrows indicate the satellite geometry with the azimuth (az) direction. Black asterisks mark the pixels corresponding to the time series in (d) and (e). Topography is from the 1 arc-sec (∼30 m resolution) Shuttle Radar Topography Mission (SRTM) Digital Elevation Model (DEM)54. d, e Time-series of cumulative LOS displacement (Cum. LOS disp.) from ascending and descending orbits, respectively, for pixels shown in (b) and (c). Negative values (range decrease) in the LOS data represent ground motions toward the satellite.
