Quaternary fault mapping within the eastern Centennial Tectonic Belt from high-resolution topography Quaternary fault mapping within the eastern Centennial Tectonic Belt from high-resolution topography
This data release presents mapping of late Quaternary fault scarps within the eastern Centennial Tectonic Belt, along the northwestern margin of the Yellowstone seismic parabola. Using 1-m light detection and ranging (lidar) data, we mapped nine faults: the Madison, Centennial, Lima Reservoir, Red Rock, unnamed faults in Hebgen Lake basin (now referred to as the “West Yellowstone basin”...
One-second USGS magnetic observatory data collected before 2013 One-second USGS magnetic observatory data collected before 2013
The USGS Geomagnetism Program operates a network of magnetic observatories that collect vector and scalar magnetometer data for use in Earth main-field modeling, geophysics research, space physics research, and space weather hazard assessment and mitigation. Until mid-2011, only 1-minute time resolution magnetic field measurements were archived with the INTERMAGNET consortium following
ShakeMap Atlas V4 and AtlasCat ShakeMap Atlas V4 and AtlasCat
The Atlas of ShakeMaps (~14,100 earthquakes, 1900-2020) provides a consistent and quantitative description of the distribution of shaking intensity for calibrating earthquake loss estimation methodologies, like those used in the USGS Prompt Assessment of Global Earthquakes for Response (PAGER) system. Version 4 of the Atlas includes a vastly expanded compilation of ShakeMaps for...
Geodetic polygons for an Alaska-Aleutian subduction zone interface earthquake recurrence model Geodetic polygons for an Alaska-Aleutian subduction zone interface earthquake recurrence model
This dataset represents polygons used to approximate areas of geodetic coupling for use in the 2023 update of the USGS National Seismic Hazard Model for Alaska.
Remote Observations of Surface Deformation for the M7.2 and M7.5 2026 Venezuela Earthquakes Remote Observations of Surface Deformation for the M7.2 and M7.5 2026 Venezuela Earthquakes
Summary: This Data Release contains surface deformation measurements resulting from the June 24, 2026, M7.2 and M7.5 Venezuela earthquakes (USGS, 2026). The earthquakes likely ruptured ~175-200 km of the Boconó and San Sebastián faults with right-lateral slip, but minimal discrete surface rupture has been identified to date. These data are based on rapid analysis of available satellite...
Seismic reflection profiles across the Puente Hills fault zone, Los Angeles, California Seismic reflection profiles across the Puente Hills fault zone, Los Angeles, California
This data release contains seismic reflection profiles acquired across the Puente Hills fault zone, Los Angeles, California. The data are high-resolution seismic reflection profiles acquired with mini-sosie (earth tamper), sledgehammer and truck-mounted mini-vibrators. Results are described in the paper: Anthonissen, C.J., L.A. Leon, F.D. Wolfe, J. Don, J.F. Dolan, J.H. Shaw, T.L. Pratt...
Data for analyzing Precariously Balanced Rocks (PBRs) in the northeastern U.S. to estimate maximum post-glacial ground motions Data for analyzing Precariously Balanced Rocks (PBRs) in the northeastern U.S. to estimate maximum post-glacial ground motions
This work describes the data used to characterize boulders and their pedestals in the northeastern U.S. (Maine, New Hampshire, Massachusetts), which are used to calculate maximum plausible earthquake magnitudes in the surrounding region as well as scaling factors for the 2023 time-independent National Seismic Hazard Model site-specific hazard curves (Petersen et al., 2024). The work...
Data for analyzing precariously balanced rocks at the Peaks of Otter, Blue Ridge Mountains of Virginia, to estimate maximum past ground motions Data for analyzing precariously balanced rocks at the Peaks of Otter, Blue Ridge Mountains of Virginia, to estimate maximum past ground motions
This work describes the data used to characterize boulders and their pedestals at the Peaks of Otter, southwest Virginia, which are used to calculate maximum plausible earthquake magnitudes in the surrounding region as well as scaling factors for the 2023 time-independent National Seismic Hazard Model site-specific hazard curves (Petersen et al., 2024). The work presents several new...
A national register of damage and losses associated with flash floods and debris flows after wildfire A national register of damage and losses associated with flash floods and debris flows after wildfire
This data release is a compilation of damage and losses stemming from historical accounts of postfire flash flood and debris-flow activity in the United States. The register spans 147 years (1879–2025) and 12 states (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, North Carolina, Oregon, Utah, Washington, and Wyoming). We compiled this information from hundreds of...
Geochronological data for the Airport East trench site, West Valley fault zone, Salt Lake County, Utah Geochronological data for the Airport East trench site, West Valley fault zone, Salt Lake County, Utah
This data release includes geochronological data for the Airport East trench site (40.795359, -111.950438) on the Taylorsville fault of the West Valley fault zone (WVFZ). The WVFZ comprises intrabasin faults in the hanging wall of the Wasatch fault zone in the northern part of Salt Lake Valley, Utah. Samples for radiocarbon and luminescence dating were collected from two paleoseismic...
Field Observations of Surface Rupture and Fault Displacement in the 2023 Mw 7.8 Pazarcık, Türkiye Earthquake Field Observations of Surface Rupture and Fault Displacement in the 2023 Mw 7.8 Pazarcık, Türkiye Earthquake
Field observations of surface rupture extent and fault displacement are critical to improving our understanding of rupture processes in the 6 February 2023 earthquakes in the Kahramanmaraş region of Türkiye. This data release includes two primary datasets depicting the 2023 moment magnitude (Mw) 7.8 Pazarcık, Türkiye earthquake rupture: 1) surface rupture mapping (lines) and 2)...
Priority Faults for Improving Seismic Hazard Models in the Intermountain West Region Priority Faults for Improving Seismic Hazard Models in the Intermountain West Region
Abstract This data release includes a list of high-priority hazardous faults and associated spatial data (regional polygons and buffered fault traces) for the Intermountain West (IMW) region of the United States. These are the top five faults or regions of concern per IMW state, based on the 2025 (version 1.0) meeting of the Basin and Range Province Earthquake Working Group. In general...
