Subsurface processes are displayed as observable ground deformations. Their identification
and monitoring provide insight about Earth’s dynamics and processes triggering these
conditions. This paper aims to show the application of remote sensing technique in obtaining
preliminary information about the subsurface through extraction of geological lineaments in
the middle fault zone of the Olkaria geothermal field. The Olkaria West Field (OWF) and East
fields are separated by a low-temperature zone; waters from the west field fracture have lower
enthalpy. Further, the wells on either side show different reservoir fluid characteristics. In this
study, Sentinel-1 Synthetic Aperture Radar (SAR) imagery was used. Image analysis
techniques used were Gray Level Co-occurrence Matrix (GLCM) for texture analysis and Line
module algorithms for edge detection to obtain the tectonic lineaments. The rose diagrams were
used to display the lineaments' orientation. The main trends observed in the lineament map for
the zone between East and West fields could be recognized as showing a major trend in S-N,
this orientation might be correlated with the fractured volcanic system of Olkaria Geothermal
field. Detection of geologic lineaments using free Sentiel-1 data presents a great advantage for
future geological surveys.
