Detailed Mapping of the 1983 Borah Peak Earthquake Surface Rupture (Idaho, USA) Using a High-Resolution Digital Terrain Model Derived from 2019 Lidar Data Detailed Mapping of the 1983 Borah Peak Earthquake Surface Rupture (Idaho, USA) Using a High-Resolution Digital Terrain Model Derived from 2019 Lidar Data
In this work, we refined and expanded the coseismic surface rupture map of the 1983 M6.9 Borah Peak earthquake coseismic rupture mapping at a scale of 1:500. While earlier work (DuRoss et al., 2019; Bello et al., 2020, 2021) used structure-from-motion (SfM) methods to construct digital elevation models (DEMs) derived from small uncrewed aerial systems (sUAS or drone) imagery, the...

This data release includes minidisk infiltration data as well as geographic data showing the location of each measurement from the Woolsey Fire, Los Angeles County, CA, USA. The Woolsey Fire burned between November 8-21, 2018. Minidisk infiltration data were obtained on November 19-21, 2018, while portions of the fire were uncontained, and prior to any rainfall. The infiltration data are...
USGS Aerial Photos of Landslides following Hurricane Helene (3-5 October 2024) USGS Aerial Photos of Landslides following Hurricane Helene (3-5 October 2024)
This data release includes aerial photos taken from a small aircraft for reconnaissance purposes (Figure 1). The photos were taken from several different types of cameras ranging from iPhones to Cannon EOS6. Camera attributes can be found in the exif data associated with each file. Photos were taken over a period of 3 days (3-5 October, 2024) to obtain general situational awareness of...
Terrestrial lidar data of debris-flow sediment in Glenwood Canyon, CO, 2021 Terrestrial lidar data of debris-flow sediment in Glenwood Canyon, CO, 2021
This release includes lidar point cloud and Wolman pebble count data for a debris-flow deposit in Glenwood Canyon, CO. The data, FullDepositRegion.las (las 1.2), were collected with a terrestrial laser scanner and includes the full deposit and portions of the slope and drainage that generated the debris flow. This .las file includes point cloud data up to 250 m upslope of the deposit...
Clay Banks Landslide Complex, Nooksack River, Washington State–landslide and river planform maps derived from aerial imagery (1933-2022) Clay Banks Landslide Complex, Nooksack River, Washington State–landslide and river planform maps derived from aerial imagery (1933-2022)
This dataset contains 17 fluvial and hillslope planforms for a 2.25 km section of the Nooksack River and adjacent Clay Banks landslide complex in northwestern Washington State spanning 1933-2022. Data include polygon and line features of river and hillslope planform structures for each year including landslides, the active river channel, the floodplain corridor, and vegetated floodplain...
Datasets documenting Surface Rupture from an Aftershock: Remote Observations from the January 2024 Wushi (Aykol) Earthquakes, China Datasets documenting Surface Rupture from an Aftershock: Remote Observations from the January 2024 Wushi (Aykol) Earthquakes, China
This data release provides shapefiles of surface rupture mapping, interferometric synthetic aperture radar (InSAR) data, finite fault modeling inputs, parameters, and outputs, and optical image cross-correlation displacement data derived from high-resolution satellite imagery to accompany the manuscript “Thompson Jobe and others, Surface Rupture From an Aftershock: Remote Observations...
Inventory of fluvial erosion and debris-flow activity following the 2020 Dolan Fire, California Inventory of fluvial erosion and debris-flow activity following the 2020 Dolan Fire, California
This data release is a geospatial record of flooding and debris-flow activity following the 2020 Dolan Fire along the central California coast. The postfire hydrologic responses documented here (“Inventory.csv”) are associated with a January 27, 2021, atmospheric river storm that hosted a narrow cold-frontal rain band, which produced intense rainfall over the burned area. Each entry in...
Landslide, soil, and vegetation measurements following an atmospheric river storm on January 9, 2023, in the Santa Ynez Mountains, California, USA Landslide, soil, and vegetation measurements following an atmospheric river storm on January 9, 2023, in the Santa Ynez Mountains, California, USA
An atmospheric river storm on January 9, 2023, produced widespread landsliding in the Santa Ynez Mountains in Santa Barbara County and Ventura County, California (USA). Landslides occurred in the footprint of the 2008 Tea Fire, 2009 Jesusita Fire, 2017 Thomas Fire, and 2019 Cave Fire, as well as in areas that had not burned in more than 15 years. Most of these landslides were shallow...
World-Wide Standardized Seismographic Network Film Chip Scans World-Wide Standardized Seismographic Network Film Chip Scans
These are the scanned digital images of microfilm copies of paper seismic records from the World-Wide Standardized Seismographic Network (WWSSN). This data set spans from 1962 to 1978 and contains about 3.7 million single-day records, which is about 5% of the entire archive. Overall the data set contains 153 magnitude 6+ earthquakes and 156 nuclear explosions. All scans were done using...
Shear-wave velocity surface seismic site characterization data at 21 sites in Puerto Rico Shear-wave velocity surface seismic site characterization data at 21 sites in Puerto Rico
In collaboration with researchers at the University of Puerto Rico, Mayaguez, the U.S. Geological Survey acquired multimethod surface seismic imaging data at 21 sites in Puerto Rico for shear-wave velocity site characterization. These data were collected at both permanent and temporary seismograph stations throughout the island, between March 6 and March 18, 2022. Data were acquired...
Time series of InSAR-derived surface deformation from 2015 – 2021 at Johns Hopkins Inlet and Gilman Glacier, Glacier Bay National Park and Preserve, Alaska Time series of InSAR-derived surface deformation from 2015 – 2021 at Johns Hopkins Inlet and Gilman Glacier, Glacier Bay National Park and Preserve, Alaska
Satellite interferometric synthetic aperture radar (InSAR) time series data were processed to investigate a large bedrock landslide above Gilman Glacier in Glacier Bay National Park and Preserve, Alaska. The time series of surface deformation for the landslide and surrounding region are presented herein. The Alaska Satellite Facility (ASF) HyP3 service (Hybrid Pluggable Processing...
Post-Wildfire Debris-Flow Hazard Assessment (PWFDF) Collection Post-Wildfire Debris-Flow Hazard Assessment (PWFDF) Collection
Wildfire can substantially alter the hydrologic response of watersheds to rainfall, and debris-flow activity is among the most destructive consequences of these events. To assist federal, state, and local agencies in planning for postfire hazards, the U.S. Geological Survey conducts debris-flow hazard assessments for recent wildfires. This collection contains the results of those...
