Landslides are geo-hazard that mostly occur in mountainous terrain and affect human lives andrndamage infrastructures. They can be triggered by natural phenomena such as earthquakes, heavyrnrains and volcanic eruptions. Construction works, legal and illegal mining, as well as thernunregulated cutting of hills (carving out land on a slope) caused most of the humaninducedrnlandslides.rnrnIn order to manage and mitigate their negative impact, landslide hazardrnzonation mapping and slope instability assessment is crucial. In this study, landslide hazardrnzonation mapping and deformation time series map for slope instability assessment werernimplemented in Birbir Mariam area. The study area is in Southern region, around 47km northeastrnof Arbaminch town. The main objective of the study was to carry out the mapping and zonationrnof landslide hazards using analytical hierarchical process of remotely sensed data and assess sloperninstability. In order to map landslide hazard zones, eight possible causative factors were studied.rnThese are slope, lineament density, drainage density, land-use and land-cover, elevation, lithology,rnnormalized difference vegetation index and aspect. These factors were compared using analyticalrnhierarchical process method to understand, which factors contribute a significant role for thernlandslide occurrences and hence analyze the zones that are vulnerable to landslide. The result ofrnthe analysis showed that, 15% (16.466kmrn) of the study area falls on very low hazard zone, 21.45rn%( 23.547kmrn2rn) within moderate hazard zone, 25.7 %(rn28.221kmrn2rn) under low hazard zone, 23 %( 25.25kmrn2rn) within very high hazard zones.rnFor the slope instability assessment in the area, a time series map was generated fromrnInterferometric Synthetic Aperture Radar by making use of sentinel-1A data from 2014 to 2019.rnThe result from this persistent scatterer InSAR analysis showed that the average displacementrnranging from +5 mm/yr. to -5.4 mm/yr. with Positive values of the displacement shows that thernarea is moving towards to line of sight while the negative values of the displacement shows thernarea is moving away from line of sight. At last by integrating information obtained from opticalrnremote sensing, PS-InSAR and a landslide inventory map a conclusion is drawn that selected areasrnin the north west, west, central and southern part of the survey area are prone to landslide hazards.
