Historic drought puts the brakes on earthflows in northern California

Abstract:

California’s ongoing, unprecedented drought is having profound impacts on the state’s resources. Here we assess its impact on 98 deep-seated, slow-moving landslides in northern California. We used aerial photograph analysis, satellite interferometry, and satellite pixel tracking to measure earthflow velocities spanning 1944 -2015 and compared these trends with the Palmer Drought Severity Index, a proxy for soil moisture and pore pressure that governs landslide motion. We find that earthflo...
