Monitoring slow moving landslides in the Berkeley Hills with TerraSAR-X data

Abstract

Large, slow moving landslides in the Berkeley Hills cause costly damage and pose a potential threat to public safety due to the close proximity of the Hayward Fault. Now in the Berkeley Hills there are four large, slow moving, deep-seated landslides. All the landslides extend through residential areas and move on the order of cm/year, each covering an area of roughly 0.25-1.00 km. Over the years, the landslides have caused costly damage to homes, breakage of underground utility pipes, and confusion over property lines. Although deformation on these landslides is typically quite small and slow, the Hayward fault runs close to the head of each landslide. It is currently not well understood how the landslides respond to seismic activity on the Hayward fault, but significant deformation is conceivable under wet conditions and a moderate to large seismic event. Space-borne Synthetic Aperture Radar (SAR) interferometry is a powerful tool for measuring movements on ground by exploiting phase difference of SAR images taken at different time instances. In this paper we aim to monitor the Berkeley Hills landslides through different SAR data especially TerraSAR-X data and time series analysis.
