Data Releases

This data release contains data from various geophysical studies performed around the larger Clayton Valley, NV area. These include reprocessed existing gravity data compiled from multiple sources, as well as newly collected gravity and ground magnetic data, and bulk densities and magnetic susceptibilities from outcrop, hand samples, and drill cores.

This digital publication contains all the geologic map information used to publish U.S. Geological Survey Geologic Investigations Map Series SIM-3143 (Sherrod and others, 2020). This geologic map shows the distribution and stratigraphic relation of volcanic, intrusive, and sedimentary units emplaced in the past 8 million years across the eight principal islands of the Hawaiian...

The U.S. Geological Survey Oregon Water Science Center, in cooperation with The Klamath Tribes initiated a project to understand changes in the surface-water extent of Klamath Marsh, Oregon and changes in groundwater levels within and surrounding the marsh. The initial phase of the study focused on developing datasets needed for future interpretive phases of the investigation. This data...

We present a preliminary point inventory of the landslides associated with the M7.2 Nippes, Haiti, earthquake that occurred on August 14, 2021. The mapping was part of rapid response efforts to identify hazards for situational awareness and emergency response by humanitarian aid organizations. This inventory accompanies an Open-File Report detailing the hazards presented by the...

The 2021 update of the U.S. National Seismic Hazard Model for Hawaii succeeds the twenty-year-old former model by incorporating new data and modeling techniques to improve the ground shaking forecasts. Output from the model includes probabilistic seismic hazard curves calculated for a 0.02° x 0.02° grid of latitude/longitude locations across Hawaii. The new model provides an expanded...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board, produced this data release that includes vector and raster geographic information systems layers used in the analysis and publication of a mean annual runoff and annual runoff variability map for 1940-2007 for Oklahoma. The data release covers all 69 8-digit hydrologic units with at least 1 square...
