| Deep soil slides, like the ones studied in this work, are driven by the development of pore pressures in the substrate during the wet PNW winter. These, and similar, slides may show pre-failure expressions as the resistance to sliding diminishes over time leading up to their collapse. Petley et al (2002) show relationships between pre-failure movement and mode-of-landsliding for field studies, while hinting at the capabilities of InSAR to perform this type of observation for landslides. This work seeks to explore the possibility of satellite-based landslide monitoring for the PNW through the pre-failure analysis of two known slides. | Deep soil slides, like the ones studied in this work, are driven by the development of pore pressures in the substrate during the wet PNW winter.
