This data release includes four files supporting Toney and others (2026), a study of the 2023 Peters Dome landslide. The Peters Dome landslide was a 6.1 million m3 ice–rock avalanche in Denali National Park and Preserve (Alaska) that occurred on September 13, 2023, local time. The coordinates of the source area are (63.1423°, -151.1871°). The files are: A CSV file of the forces exerted...

This data release provides a point inventory of rainfall-induced landslides in Puerto Rico during 2022 and 2023. Each record includes the date, latitude, longitude, descriptive location, spatial confidence, reporting source, and reference link. Landslides were identified from public reports, municipal sources, and National Weather Service call logs. Verification required dated...

In 2001, the Alaska Division of Geological & Geophysical Surveys (DGGS) published a database compiling geotechnical borehole and well-log records in Anchorage, Alaska (Combellick and others, 2001). This data release builds on that database, adding some additional cone penetration test (CPT) and well log records in broader areas across the state (Alaska Department of Natural Resources...

This data release contains datasets associated with the 2025 U.S. Geological Survey (USGS) National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The 2025 PRVI NSHM (Shumway and others, 2025), which is an update of the original 2003 PRVI NSHM (Mueller and others, 2003, 2010). Datasets include model inputs like seismicity catalogs, smoothed seismicity...

Earthquake catalogs are essential data inputs for seismic hazard modeling. Because earthquake magnitudes are reported in a variety of types (e.g., local magnitudes, moment magnitudes), magnitude conversion relationships must be used to convert the different magnitude types present in a catalog to a uniform magnitude type to avoid biases in the hazard computation. However, these...

This data release complements the following publication: D.E. Goldberg and others (2025). Ultralong, supershear rupture of the 2025 Mw 7.7 Mandalay earthquake reveals unaccounted risk. Science 390, 458-462. https://doi.org/10.1126/science.ady3581 It contains the preferred model results published in the manuscript referenced above. It also contains the input data and model parameters...

As part of an effort by the U.S. Geological Survey (USGS) to better understand topographic and structural conditions that promote slow spreading and sagging of mountain ridges (Varnes and others, 1989), USGS researchers began surveying monitoring points at Bald Eagle ridge in the Sawatch Range of Colorado in 1975 (Radbruch-Hall and others, 1976; Varnes and others, 1990). Bald Eagle ridge...

Bald Eagle ridge, located about 14 km west of Leadville, Colorado, is slowly spreading and sagging, resulting in sackungen that have been monitored by the U.S. Geological Survey (USGS) since the mid-1970s (for example, Varnes and others, 1989; Varnes and others, 1990; Varnes and others, 2000). The ridge forms the southeastern flank of the glaciated Busk Creek valley and is underlain by

A Smart Dynamic Cone Penetrometer (DCP) system allows for the partially automated collection of cone penetrometer data (CPT) to determine mechanical properties of soil along a vertical profile. A smart DCP system was used to collect soil penetration-with-depth values at 19 sites across the mountainous regions of Puerto Rico. The 19 sites were co-located at the United States Geological...

Earthquake ground motions are modified by local geologic site conditions. Soft soils and basin sediments may amplify and prolong the duration of ground shaking, necessitating site characterization to improve existing ground motion predictions and seismic hazard analyses. Horizontal-to-Vertical Spectral Ratio (HVSR) measurements distinguish one or more site resonant frequencies and the...

This data release contains datasets that depict fault rupture and surface displacement from the M7.7 Mandalay, Myanmar, earthquake on March 28, 2025. The earthquake caused ~475 km of right-lateral surface rupture on the Sagaing fault in Myanmar. These data were based on rapid analysis of available satellite data after the earthquake and updated as more information became available. They...
