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...
Datasets documenting Timescales of surface faulting preservation in low-strain intraplate regions from landscape evolution modeling and the geomorphic and historical record Datasets documenting Timescales of surface faulting preservation in low-strain intraplate regions from landscape evolution modeling and the geomorphic and historical record
This data release provides input data and landscape evolution modeling results to accompany the manuscript “Timescales of surface faulting preservation in low-strain intraplate regions from landscape evolution modeling and the geomorphic and historical record" (Thompson Jobe and Reitman, 2025). The data release includes two tabular datasets, a text file, and movies of the landscape...
News-reported landslide impacts in Southeast Alaska, 1990-2024 News-reported landslide impacts in Southeast Alaska, 1990-2024
1. Abstract Landslides are common across Southeast Alaska (SEAK) and have caused damages and fatalities in populated areas. Better understanding of landslide triggering conditions and impacts can inform risk reduction strategies and alerting efforts. Landslide inventory data with weekly to hourly time resolution are needed to quantify these conditions. Local news sources are a source of...

Preliminary Landslide Hazard Estimate Maps for the 2024 Hurricane Helene Landslide Emergency Response Preliminary Landslide Hazard Estimate Maps for the 2024 Hurricane Helene Landslide Emergency Response
This data release includes relative landslide hazard estimate maps for the southern Appalachian Mountains affected by Hurricane Helene (September 26-27, 2024) and the heavy rainfall that preceded it (September 23-26, 2024). The two modeling approaches used were adapted from existing models and were run in early October 2024 using initial precipitation estimates to produce rapid event...
Site Amplification Factors for the Walnut Creek and Concord Regions of the San Francisco Bay, California Site Amplification Factors for the Walnut Creek and Concord Regions of the San Francisco Bay, California
This data release contains rasterized data sets of point values of site amplification for the Walnut Creek and Concord regions of the San Francisco east bay. Hartzell et al. (2024) covers the associated field work and the source-site inversion method used to obtain the site response spectra. Site amplification values are given for the geometric average over four frequency ranges (0.5 to...
Landslide Inventory for Pohnpei, Federated States of Micronesia (FSM) 2003 - 2023 Landslide Inventory for Pohnpei, Federated States of Micronesia (FSM) 2003 - 2023
Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery. Mapping was done using RGB satellite imagery from Maxar, Planet...
