AbstractIn this study, we used interferometrically derived images, from several radar satellites (RADARSAT, ERS and ENVISAT), to monitor current post slide motion at the Frank Slide, a 30x 106m3slide-rock avalanche, in the Canadian Rockies. The images cover the period from July 1993 to June 2004. Our results show that the Frank slide is still active and the deformation process is localized and are related to seasonal and local weather conditions. This information is useful in assisting to locate in-situ field monitoring at specific locations, and to plan mitigation strategies. The combination of satellite differential InSAR techniques, covering large areas, and site-specific GPS monitors can produce an integrated monitoring system of active slopes.
