Data

This data release provides results from laboratory testing of 49 regolith specimens obtained from landslide-prone terrain in Puerto Rico, USA. Specimens were obtained by hand either from the ground surface or from the subsurface using boreholes and hand-excavated pits to a maximum depth of 110 cm. Specimen depths are reliably indicated in the file “Tests-performed.csv” and less reliably...

Landslide hazards pose a serious threat to people and infrastructure across the Federated States of Micronesia (FSM). To support hazard assessment and mitigation efforts, the USGS Landslide Disaster Assistance Team (LDAT) produced a landslide susceptibility and runout map for Pohnpei State using a digital elevation model (DEM) and Grfin Tools modeling (Cronkite-Ratcliff and others, 2025...

Landslide hazards pose a serious threat to people and infrastructure across the Federated States of Micronesia (FSM). To support hazard assessment and mitigation efforts, the USGS Landslide Disaster Assistance Team (LDAT) produced a landslide susceptibility and runout map for Chuuk State using a digital elevation model (DEM) and Grfin Tools modeling (Cronkite-Ratcliff and others, 2025...

Landslide hazards pose a serious threat to people and infrastructure across the Federated States of Micronesia (FSM). To support hazard assessment and mitigation efforts, the USGS Landslide Disaster Assistance Team (LDAT) produced a landslide susceptibility and runout map for Kosrae State using a digital elevation model (DEM) and Grfin Tools modeling (Cronkite-Ratcliff and others, 2025...

This dataset includes photos taken in the field (Final_photos_for_data_release.zip) and a shapefile (Blackhollow_de.shp stored in Blackhollow_de.zip) to document debris flow activity in the Black Hollow watershed. The Black Hollow watershed was burned by the Cameron Peak Fire (13 August to 2 December 2020) and experienced a debris flow on 20 July 2021. The polygon shapefile in this...

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 runout assessments. This collection contains the results of those assessments conducted...

This dataset provides precipitation intensity estimates for a one-year recurrence interval for the Continental United States as cloud-optimized GeoTIFFs (COGs). The release includes COGs for 15-minute, 30-minute, and 60-minute rainfall durations, and the precipitation intensities for these durations are referred to as I15, I30, and I60, respectively. Each raster reports precipitation...

The data contained in this Data Release depicts surface deformation and surface slip distribution for the 2023 Mw 7.8 Pazarcık and 7.5 Elbistan, Türkiye, earthquakes derived from subpixel correlation of Planet Dove and Sentinel-2 (S2) optical satellite images. The datasets contained in this data release are (1) raster files of surface displacement fields in north-south and east-west...

This data release contains preliminary point locations of potential landslides and snow avalanches triggered by the M7.0 Hubbard Glacier Earthquake based on a Synthetic Aperture Radar (SAR) change map by Eiden (2025). This SAR change map was the first publicly available post-event radar or optical dataset covering the earthquake region. The map reflects changes in the backscattering...

This Data Release provides synthetic probability density functions used in the geologic deformation model as part of the 2025 National Seismic Hazard Model update for Puerto Rico-U.S. Virgin Islands. We include files implemented in the earthquake rupture forecast using the inversion framework. Modeling philosophy and methodologies are described in the interpretative companion manuscript...

This Data Release contains two compilations provide information on the date of the last known earthquake in the U.S. where available (conterminous U.S. and Alaska). There are two spatial datasets with different feature geometries — line features (“HistDOLE_v1”) and point features (“PaleoDOLE_v1”). The line features describe surface ruptures constrained by historical or near-historical...

This data release contains files supporting the publication “Landslide volume estimation from seismic waveform features using a global catalog of seismogenic events” (Collins and others, 2026). Events.csv lists each landslide event used in the publication, published event ids, names, times, locations, and volumes taken from Seismogenic Landslides and other Mass Movements (ver. 3.0, May...
