From late December 2022 to January 2023, a series of atmospheric river storms produced widespread landsliding in the San Francisco Bay area of California. USGS scientists performed reconnaissance field work to document the extent of landsliding in the region and compiled reports of landslides from media and California Highway Patrol (CHP) reports. This data release documents locations of road cut and shallow hillslope landslides triggered between December 31, 2022 and January 18, 2023. This inventory is not intended to be a complete inventory, but a reporting of observations made with limited time and resources. The point locations include descriptions and associated attributes, described in the metadata. Media...

Landslides in the San Francisco Bay area (SFBA) of California impact people, infrastructure, and the environment, and are commonly induced by intense or prolonged rainfall associated with strong winter storms. Both shallow (<3 meter) and deep (≥3 meter) landslides can occur. Typically, shallow landslides occur as a result of high-intensity precipitation when the ground is already nearly saturated with water from previous storms. These types of events typically occur during the height of the rainy season, from December through February. Deep-seated landslides can also initiate or renew movement during these times but are also often triggered during the spring months (March through May), when water from rainfall has...
