dc.description.abstractUnderstanding seasonal processes is paramount in characterizing hazard of slow-moving landslides, but is often limited by the temporal and spatial resolution of ground-based and satellite data. Here we use time-series analysis of 2009-2014 TerraSAR-X InSAR data with as low as 11-day repeat pass and 463, 372 pixels covering the four slow-moving landslides in the Berkeley Hills region of northern California. These slides cause long-term structural damage to buildings and underground infrastructure. Combination of TerraSAR-X observations with ascending RSAT2 observations allows an estimation of vertical and downslope horizontal components of motion for each slide. Using the more robust TerraSAR-X satellite data, we then use Principal Component and Independent Component Analyses (PCA and ICA, respectively), to isolate four components of slide motion at each of four slides. Three of these trends exhibit seasonal components of motion. Cross-correlation with temperature and precipitation show complex relationships between hillslope motion and seasonal cyclings, and a direct relationship between slide cumulative precipitation and slide acceleration at a lag of 30 days.
