Digital elevation models, orthophotos, and differencing results to analyze the effect of land cover type on 3D deformation recovery from synthetically deformed high-resolution satellite optical imagery Digital elevation models, orthophotos, and differencing results to analyze the effect of land cover type on 3D deformation recovery from synthetically deformed high-resolution satellite optical imagery
Synthetic earthquake deformation was imposed on high resolution (~0.5 m/pixel)orthoimagery and digital elevation models (DEMs) for two regions of the Garlock fault in the east and west. This repository contains the input and result rasters for the analysis, further described in Hanagan et al. (2025): "Effect of land cover type on 3D deformation recovery from synthetically deformed high...
Landslides Triggered by the 2025 M8.8 Kamchatka Peninsula, Russia Earthquake Landslides Triggered by the 2025 M8.8 Kamchatka Peninsula, Russia Earthquake
We present an inventory of 346 landslides triggered by the July 29, 2025 M8.8 Kamchatka Peninsula, Russia earthquake. Landslides were mapped from 10 meter resolution openly available Sentinel-2 optical images. All landslides were manually identified by comparing pre- (using cloud free images as close to the earthquake date as possible from July 2024 - 2025) and post-earthquake real color...
Age-model codes and paleoearthquake ages for the Frazier Mountain, Pallett Creek, and Wrightwood paleoseismic sites along the Southern San Andreas Fault, California Age-model codes and paleoearthquake ages for the Frazier Mountain, Pallett Creek, and Wrightwood paleoseismic sites along the Southern San Andreas Fault, California
These datasets provide age-model codes and resultant paleoearthquake age distributions for three paleoseismic sites along the southern San Andreas Fault. The code format is compatible with the age-model program OxCal (Bronk Ramsey 2009) which calibrates radiocarbon dates to calendar years and uses stratigraphic relationships among radiocarbon samples and sedimentary units to compute
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...
