Detailed Description
California is one of the most geologically diverse states in the nation, the second most seismically active, and first in seismic risk with a population approaching 40 million. Climate regimes span from deserts to temperate rain forests, and its geologic framework consists of hard crystalline rocks, to soft unconsolidated sediment spanning Paleoproterozoic to Quaternary. Across California’s eleven geomorphic provinces, from basins below sea level to peaks over 14,000 feet, this presentation will highlight case studies spanning the range of landslide processes and types within California’s diverse settings.

Caption: Rockslide on California State Route 70 in the Feather River Canyon, Butte/Plumas county line, northern California. This slide was triggered on October 24, 2021 by a Category 5 atmospheric river, which released more than ten inches of rain in the area over a 48-hour period. Approximately seven thousand cubic yards of rock and debris buried and closed the highway.
