A national register of damage and losses associated with flash floods and debris flows after wildfire A national register of damage and losses associated with flash floods and debris flows after wildfire
This data release is a compilation of damage and losses stemming from historical accounts of postfire flash flood and debris-flow activity in the United States. The register spans 147 years (1879–2025) and 12 states (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, North Carolina, Oregon, Utah, Washington, and Wyoming). We compiled this information from hundreds of...
Geochronological data for the Airport East trench site, West Valley fault zone, Salt Lake County, Utah Geochronological data for the Airport East trench site, West Valley fault zone, Salt Lake County, Utah
This data release includes geochronological data for the Airport East trench site (40.795359, -111.950438) on the Taylorsville fault of the West Valley fault zone (WVFZ). The WVFZ comprises intrabasin faults in the hanging wall of the Wasatch fault zone in the northern part of Salt Lake Valley, Utah. Samples for radiocarbon and luminescence dating were collected from two paleoseismic...
Field Observations of Surface Rupture and Fault Displacement in the 2023 Mw 7.8 Pazarcık, Türkiye Earthquake Field Observations of Surface Rupture and Fault Displacement in the 2023 Mw 7.8 Pazarcık, Türkiye Earthquake
Field observations of surface rupture extent and fault displacement are critical to improving our understanding of rupture processes in the 6 February 2023 earthquakes in the Kahramanmaraş region of Türkiye. This data release includes two primary datasets depicting the 2023 moment magnitude (Mw) 7.8 Pazarcık, Türkiye earthquake rupture: 1) surface rupture mapping (lines) and 2)...
Priority Faults for Improving Seismic Hazard Models in the Intermountain West Region Priority Faults for Improving Seismic Hazard Models in the Intermountain West Region
Abstract This data release includes a list of high-priority hazardous faults and associated spatial data (regional polygons and buffered fault traces) for the Intermountain West (IMW) region of the United States. These are the top five faults or regions of concern per IMW state, based on the 2025 (version 1.0) meeting of the Basin and Range Province Earthquake Working Group. In general...

Inventory of Large Slope Instabilities, Central and Eastern Prince William Sound, Alaska Inventory of Large Slope Instabilities, Central and Eastern Prince William Sound, Alaska
Steep landscapes shaped by glaciers, particularly areas where ice has recently retreated, often experience gravitationally driven slope deformation. We refer to hillslopes that show evidence of such deformation as bedrock instabilities. These deep-seated instabilities may or may not develop into coherent landslides with through-going basal sliding surfaces. In coastal environments...
Liquefaction potential index calculations at cone penetration test sites in California Liquefaction potential index calculations at cone penetration test sites in California
This data release provides tabulated liquefaction potential index (LPI) values for a standard set of earthquake magnitudes (M) in the range 4.5-9, peak ground accelerations (PGA) in the range 0-1.0 g, and groundwater depths (GWD) in the range 0-15 m, as described in detail in Engler and others (2025). We use these data to rapidly interpolate LPI values for any M-PGA-GWD combination. The...
The U.S. Geological Survey Global Vs30 Mosaic The U.S. Geological Survey Global Vs30 Mosaic
This data release provides the global mosaic of the time-averaged shear-wave velocity in the upper 30 m (Vs30) described by Heath and others (2020a). This map uses the Wald and Allen (2007) slope-based Vs30 as the basemap, and regional maps take precedence where they are available. This is an update to the Heath and others (2020b) data release. Changes include updates to the data sources...
Displacement and groundwater pressure data from the Carmel Knoll and Johnson Creek landslides, Oregon, USA Displacement and groundwater pressure data from the Carmel Knoll and Johnson Creek landslides, Oregon, USA
Coastal landslides such as the Carmel Knoll and Johnson Creek landslides located in Lincoln County, Oregon, reactivate during most winter rainy seasons when groundwater pressures are elevated. We collected landslide displacement and groundwater pressure head data at 15-minute to 60-minute intervals using solar- and battery-powered dataloggers at the aforementioned landslides to assist...
Elevation difference products, schematic flow path, and volume polygons for the August 15, 2023 debris flow in Tahoma Creek, Mount Rainier Elevation difference products, schematic flow path, and volume polygons for the August 15, 2023 debris flow in Tahoma Creek, Mount Rainier
This dataset includes digital surface model (DSM) products, photographs, and shapefiles associated with the August 15, 2023 debris flow in Tahoma Creek at Mount Rainier, Washington. In this study, we created a post-event DSM using The Surface Extraction with TIN-based Search-space Minimization (SETSM) algorithm (Noh and Howat, 2017) using WorldView-2 stereo images collected on July 14...

Global Positioning System survey data from 2014-2022 on the West Salt Creek rock avalanche deposit, Mesa County, Colorado Global Positioning System survey data from 2014-2022 on the West Salt Creek rock avalanche deposit, Mesa County, Colorado
The West Salt Creek rock avalanche (refer to Figure 1 for location, .pdf and .jpg files are provided) occurred on May 25, 2014, and filled the West Salt Creek valley with a hummocky deposit that ranged up to ~38 m thick (White and others, 2015; Coe and others, 2016). The central core of this deposit continued to move for at least one hour after other parts of the deposit had stopped...
