San Francisco Bay Area Reconnaissance Landslide Inventory, January 2023

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 and CHP reports supplemented the field work, but do not represent a complete compilation of all landslide reports available during this time frame. This data release includes: 1) .csv file containing descriptive attributes, and point locations of road cut failures and shallow hillslope landslides, 2) .zip file containing photographs associated with point locations, and 3) .zip file containing shapefile (.shp) of approximate travel paths of USGS scientists, indicating the extent of area explored.
