The Sumatran Fault Zone (SFZ), Indonesia is a tectonically active region characterized by frequent seismic activity and significant geological features. In this study, we conducted a preliminary analysis using the Interferometric Synthetic Aperture Radar (InSAR) to asses the slip rate on the Manna Fault in the Sumatran Fault Zone (SFZ). We used ALOS PALSAR 1 satellite imagery to obtain information on deformation from the period 2007 to 2011 using the Small Baseline Subset (SBAS) method. Fault parallel velocities estimation from InSAR show the typical right-lateral slip of the Manna Fault. The slip rate of the Manna Fault estimated from this study is 8.6 mm/year. This study shows the potential of using InSAR with ALOS PALSAR I in monitoring slip rate in the Sumatra region. The InSAR technology can improve our understanding of seismic activity and potential earthquake hazards in the south Sumatra.
