Abstract
Interferometry synthetic aperture radar (InSAR) was used to detect the precursor movement of the East Branch of East Weaver Creek landslide four years prior to the significant failure in 2011. By using measurements calculated from the InSAR imagery and statistical modeling, the movement was correlated to spring storm events and single maximum precipitation events that occurred between the years of 2007 to 2010, specifically during the months of March and April. The 2011 failure further correlates this pattern with the rapid mobilization of sediment during a similar storm event that occurred during the months of March and April in 2011.
