Landslide susceptibility analysis for Bududa District using D-InSAR technique

Abstract

Landslide susceptibility analysis seeks to establish the risk of an area’s likelihood to be affected by landslides. This can be estimated through ground deformation measurements using DInSAR or GPS. DInSAR is all-weather, penetrates tree canopies etc. GPS is highly accurate at high sampling and temporal monitoring. It is critical to measure ground deformation in landslide prone areas because prior to a landslide occurrence, ground deformation happens incrementally. Different methods have been applied and these include GPS and DInSAR. These have different strengths and weaknesses. This study aimed at comparing the 2 techniques to improve ground deformation measurements in Bududa. I found out that DInSAR closely approximates the results obtained by GPS.
