Simplified frontal thrust splay fault geometries at the Cascadia Subduction Zone mapped using multi-channel seismic (MCS) reflection data Simplified frontal thrust splay fault geometries at the Cascadia Subduction Zone mapped using multi-channel seismic (MCS) reflection data
This dataset contains offshore fault geometries for frontal thrust splay faults in the Cascadia Subduction Zone (CSZ) that were mapped and developed for use in 3D ground motion simulations (Dunham and others, 2025). There are a total of 6 thrust faults (A-F), three of the faults (A-C) were mapped by interpretation of seismic reflection data (Ledeczi and others, 2024; Lucas and others...
Simulated lahar arrival times and maximum depths in the Middle Fork Nooksack River drainage, resulting from hypothetical landslide sources on the western summit of Mount Baker, Washington Simulated lahar arrival times and maximum depths in the Middle Fork Nooksack River drainage, resulting from hypothetical landslide sources on the western summit of Mount Baker, Washington
This data release contains postprocessed D-Claw model output, simulation configuration, and provenance information for six hypothetical lahar scenarios at Mount Baker, Washington. The modeled scenarios evaluate the influence of landslide source volume and material properties on lahar dynamics, inundation, and runout in the Middle Fork Nooksack River drainage. The numerical simulations...
Simulated Snow and Hydrometeorology Variables for the Upper Snake River Basin Headwaters and Surrounding Area under Historical (1981-2020) and Mid-Century Pseudo-Global Warming Conditions using CONUS404 Simulated Snow and Hydrometeorology Variables for the Upper Snake River Basin Headwaters and Surrounding Area under Historical (1981-2020) and Mid-Century Pseudo-Global Warming Conditions using CONUS404
This data release contains historical and future climate SnowModel (Liston and Elder, 2006; Liston and others, 2020; Liston, 2020) simulation outputs on a 90-meter (m) geospatial grid for a 216-kilometer (km) x 327-km model domain in the Upper Snake River Basin. The historical simulation (control, CTL) was run from water years 1981 to 2020 using the CONUS404 meteorology dataset...
Simulated Snow and Meteorology Variables, Qashqadaryo Region, Uzbekistan, 1950-2023 Simulated Snow and Meteorology Variables, Qashqadaryo Region, Uzbekistan, 1950-2023
This data release contains output from a numerical snow simulation for a 166 kilometer (km) × 160 km model domain in the Qashqadaryo region of Uzbekistan. The simulation encompasses key watersheds within the region and uses SnowModel (Liston and Elder, 2006; Liston and others, 2020; Liston, 2020) to estimate the snow water resources and meteorology across the simulation domain. The...
Simulation and modeling output and geospatial data from the 2023 Peters Dome landslide (Alaska) Simulation and modeling output and geospatial data from the 2023 Peters Dome landslide (Alaska)
This data release includes four files supporting Toney and others (2026), a study of the 2023 Peters Dome landslide. The Peters Dome landslide was a 6.1 million m3 ice–rock avalanche in Denali National Park and Preserve (Alaska) that occurred on September 13, 2023, local time. The coordinates of the source area are (63.1423°, -151.1871°). The files are: A CSV file of the forces exerted...
Simulation-based scenario ShakeMaps for large magnitude (Mw6.5+) crustal earthquakes on the Seattle, Tacoma, and southern Whidbey Island faults, Washington, USA (ver. 1.1, June 2026) Simulation-based scenario ShakeMaps for large magnitude (Mw6.5+) crustal earthquakes on the Seattle, Tacoma, and southern Whidbey Island faults, Washington, USA (ver. 1.1, June 2026)
This dataset consists of 3-component acceleration timeseries that describe ground shaking from simulated Mw6.5+ earthquakes on the Seattle, Tacoma, and southern Whidbey Island faults in Washington State. These were produced in support of the development of simulation-based scenario ShakeMaps, as described in Stone et al. (2026). Individual scenarios span a variety of different source...
Single-Beam Bathymetry and Sediment Data From Vibracores Collected at Lake Maggiore, St. Petersburg, Florida Single-Beam Bathymetry and Sediment Data From Vibracores Collected at Lake Maggiore, St. Petersburg, Florida
In July 2025, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) collected single-beam bathymetry (SBES) data and sediment vibracores at Lake Maggiore, St. Petersburg, Florida. These data were collected during USGS field activity number (FAN) 2025-309-FA. The SBES data were collected using USGS research vessel (R/V) MAKO. The...
Site, Visit, Survey, and eDNA Data for Limestone Salamanders (Hydromantes brunus) from Mariposa County, California, 2024-2025 Site, Visit, Survey, and eDNA Data for Limestone Salamanders (Hydromantes brunus) from Mariposa County, California, 2024-2025
Limestone salamanders (Hydromantes brunus) are cryptic terrestrial salamanders about which little is known, including their distribution. Because the salamanders are difficult to detect, survey protocols that estimate detection probabilities are needed to interpret the meaning of negative (non-detection) surveys and better understand the distribution of the salamanders. This study...
SNP Genotype Data of Brodiaea filifolia and Brodiaea santarosae Collected in 2025 from Riverside, Orange, and Los Angeles Counties of Southern California SNP Genotype Data of Brodiaea filifolia and Brodiaea santarosae Collected in 2025 from Riverside, Orange, and Los Angeles Counties of Southern California
This data release includes genotype data for 131 Brodiaea filifolia and 35 Brodiaea santarosae collected throughout Riverside, Orange, and Los Angeles counties in southern California in 2025. The samples were sequenced with restriction site-associated sequencing (RAD-seq) and genotyped at 166,974 single nucleotide polymorphisms (SNPs). Short sequence reads generated for this project are...
Soil Characteristics and Sediment Deposition Rates Across Intertidal Habitats in Morro Bay, California Soil Characteristics and Sediment Deposition Rates Across Intertidal Habitats in Morro Bay, California
Assessing the spatial variation in accretion rates and soil properties helps increase understanding of tidal wetland processes and can be used to calibrate model of long-term wetland resilience. Nine deep soil cores (50-100 centimeters) were sampled across tidal flat, tidal marsh, and upland transition areas across Morro Bay estuary. Short (7 centimeters) soil cores were also sampled...
