Southern Kenya Rift has been known as a region of high geodynamic activity expressed
by recent volcanism, geothermal activity and high rate of seismicity. The active faults
that host these activities have not been investigated to determine their subsurface
geometry, faulting intensity and constituents (fluids, sediments) for proper
characterization of tectonic rift extension. Two different models of extension direction
(E–W to ESE–WNW and NW–SE) have been proposed. However, they were based on
limited field data and lacked subsurface investigations. In this research, we delineated
active fault zones from ASTER image draped on ASTER DEM, together with relocated
earthquakes.
