Multiple subaerial landslides adjacent to Prince William Sound, Alaska (for example, Dai and others, 2020; Higman and others, 2023; Schaefer and others, 2024) pose a threat to the public because of their potential to generate ocean waves (Dai and others, 2020; Barnhart and others, 2021; Barnhart and others, 2022) that could impact towns and marine activities. One bedrock landslide on the west side of Barry Arm fjord drew international attention in 2020 because of its large size (~500 M m3) and tsunamigenic potential (Dai and others, 2020). As part of the U.S. Geological Survey response to the detection of the potentially tsunamigenic landslide at Barry Arm, as well as a broader effort to evaluate bedrock landslide...

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...

This data release includes information used to support the manuscript "Linking mesoscale meteorology with extreme landscape response: effects of narrow cold frontal rainbands (NCFR)". The included datasets and supplement include information related to the 22 March 2018 NCFR and associated shallow landslides in the Toulumne Canyon triggered by this event. The three datasets and one supplemental information document are: 1) mapped landslides where we created polygons for each landslide that occurred (Tuolumne Canyon Landslide Data Storm of 22 March 2018.kmz), 2) soil grain size data for landslide source and depositional zones (Tuolumne Canyon Grain Size Data Storm of 22 March 2018.xlsx), 3) a time series of rainfall...

The winter rainy season of 2016-2017 brought abundant rainfall to the state of California, including the San Francisco Bay region. Thousands of shallow landslides were triggered as a result of saturated soils and intense rainfall from strong winter storms in January and February 2017. The highest concentration of landslides from these storms occurred in the eastern part of the bay region, where landslides in the hills east of the Cities of Richmond, Berkeley, Oakland, Hayward, and Fremont, and elsewhere in the region, damaged homes, displaced a major electrical transmission-line tower, and blocked several heavily traveled state highway routes. The data presented here support our published map titled, "Landslides...

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...
