Preliminary Geology of the North Meadow Creek Area, Tobacco Root Mountains, Southwest Montana: Measurements along the North Meadow Creek Fault Preliminary Geology of the North Meadow Creek Area, Tobacco Root Mountains, Southwest Montana: Measurements along the North Meadow Creek Fault
A previously unmapped fault forms a low scarp on a terrace along North Meadow Creek, a drainage on the east flank of the Tobacco Root Mountains, in SW Montana. The fault extends ~7.5 km between points where it disappears beneath alluvium of Madison Valley, on the SE, and glacial moraines on the NW. It appears on neither the Geologic Map of Montana nor the Quaternary Fault and Fold...
High frequency and region-scale simulations of large (Mw7+) earthquakes on the southern Whidbey Island fault, Washington, USA High frequency and region-scale simulations of large (Mw7+) earthquakes on the southern Whidbey Island fault, Washington, USA
This dataset consists of 3-component velocity time-series that describe ground shaking from simulated Mw7+ earthquakes on the southern Whidbey Island fault in Washington state. These were produced in support of the research project described in Stone et al. (2025) "High frequency and region-scale simulations of large (Mw7+) earthquakes on the southern Whidbey Island fault, Washington...
Compositional and Hydrothermal Frictional Strength Data for Five Chlorite Gouges Compositional and Hydrothermal Frictional Strength Data for Five Chlorite Gouges
A series of hydrothermal frictional strength experiments was conducted on synthetic gouges prepared from five chlorite-rich samples of varying composition. We present chlorite mineral compositions obtained by electron microprobe techniques, and X-ray diffraction and bulk chemical analyses of the gouges that were prepared by hand-grinding each sample to less than 90-µm grain diameter...
Lidar point cloud, raster, and RTK GNSS survey data for pre- and post-restoration of Ackerson Meadows, Yosemite National Park, California, USA Lidar point cloud, raster, and RTK GNSS survey data for pre- and post-restoration of Ackerson Meadows, Yosemite National Park, California, USA
A collection of lidar point cloud, raster, and real-time kinematic global navigation satellite system (RTK GNSS) survey data of Central and South Ackerson Meadow to aid in monitoring wetland meadow restoration. Uncrewed aircraft system (UAS) lidar collections were flown in June 2023 (before restoration), November 2023, and November 2024 (after restoration), with one forthcoming...
Data for A 3-D Seismic Velocity Model for Cascadia with Shallow Soils & Topography, Version 1.7 Data for A 3-D Seismic Velocity Model for Cascadia with Shallow Soils & Topography, Version 1.7
This data release contains three netCDF4 files containing grid points of P- and S-wave seismic velocities in Cascadia. This model is an update to Stephenson et al. (2017) Open-File Report 2017-1152, and contains a newly added shallow soil model and optional user-specified topography. A description of the model and its development is provided in the associated Open-File Report. The grid...
Observations of offset from shallow aseismic slip on the Concord fault, San Francisco Bay Area, CA Observations of offset from shallow aseismic slip on the Concord fault, San Francisco Bay Area, CA
The Concord fault is an active strike-slip fault of the Pacific-North America plate boundary that runs through suburban eastern San Francisco Bay Area, Contra Costa County, CA, in the cities of Concord and Walnut Creek. Recent work has identified ongoing aseismic slip along the trace of the fault and clarified its location. The data presented here record evidence of tectonic offsets of...
High-resolution seismic imaging data from the West Napa Fault Zone acquired in 2015 at Hendry Winery, Napa, California High-resolution seismic imaging data from the West Napa Fault Zone acquired in 2015 at Hendry Winery, Napa, California
In February 2015, the U.S. Geological Survey conducted a high-resolution seismic survey across the West Napa Fault zone at Hendry Winery in Napa, California (Fig. 1). Geophones were deployed every 3 to 5 meters along a southwest-northeast trend to create an approximately 400-m-long linear array. Data were recorded by two Geometrics Stratavisor NZ-60TM seismographs. Both P-wave and S-wave...
Gridded earthquake ground motions for the 2023 ASCE/SEI 41 Standard outside of the conterminous United States Gridded earthquake ground motions for the 2023 ASCE/SEI 41 Standard outside of the conterminous United States
For evaluating and retrofitting existing buildings to resist earthquakes, the 2023 ASCE/SEI 41 Standard provides Basic Safety Earthquake spectral response accelerations at four levels (BSE-1N, BSE-2N, BSE-1E, and BSE-2E). This data release covers BSE-1E and BSE-2E spectral response accelerations for sites outside of the conterminous United States. For sites in the conterminous U.S., BSE...
An Open Repository of U.S. Cone Penetration Test (CPT) data An Open Repository of U.S. Cone Penetration Test (CPT) data
Cone Penetration Test (CPT) data collected by the U.S. Geological Survey since 1978 are compiled and provided as a uniformly formatted set of comma separated value (.csv) files. This dataset includes 1822 CPT soundings from 14 U.S. States. Provided CPT data are a set of three column comma separated value (.csv) files containing depth (meters), tip resistance (̨MPa), and sleeve resistance...
Ring widths, scans of samples, and ancillary data from Sequoia sempervirens (coast redwood) trees and stumps at Fort Ross and Gualala, sampled for dendroseismology in 2021–2024 Ring widths, scans of samples, and ancillary data from Sequoia sempervirens (coast redwood) trees and stumps at Fort Ross and Gualala, sampled for dendroseismology in 2021–2024
Sequoia sempervirens (coast redwood) trees were sampled for a dendroseismological investigation along the North Coast Section of the San Andreas Fault, and the data were fully analyzed, interpreted, and discussed in a journal article and supplemental material (Carroll et al., 2025). Here, were provide data associated with this work: 1200 dpi resolution images of tree cores and stumps...
Point cloud and digital elevation data from terrestrial laser scanning of the San Andreas Fault and coast redwood trees near Fort Ross, California Point cloud and digital elevation data from terrestrial laser scanning of the San Andreas Fault and coast redwood trees near Fort Ross, California
These data are derived from laser scanning surveys of the San Andreas Fault and surrounding groves of trees in Fort Ross State Historic Park, California. Surveys were performed on May 13, 2013 and June 19–20, 2024. The second survey was performed specifically to document the morphology of trees that show signs of past earthquake damage, four of which were sampled for dendroseismology...
Scanned Recordings of the Rangely, Colorado (USA) Earthquake Control Experiment (1972) Scanned Recordings of the Rangely, Colorado (USA) Earthquake Control Experiment (1972)
These are scanned recordings from the Rangely earthquake control experiment that took place from 1969-1974 in the area surrounding Rangely, Colorado. Data were telemetered to Menlo Park, California, where they were recorded on develocorder films. Twelve stations with a total of fourteen channels were recorded and are available in this data set. Data were collected by the US Geological...
