The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is that the May 18 eruption marked the beginning of a period of eruptive activity that lasted through 1986. Beginning in October 1980, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most...

This data release includes outputs that were created using Monte Carlo simulations with the aim to reduce elevation overestimation in coastal wetlands at Grand Bay, MS. We evaluated the performance of coastal wetland elevation refinement by using bare earth digital elevation models (DEMs) and DEMs created from the last return from the light detection and ranging (lidar) point cloud...

This data release includes digital elevation models (DEMs) that were created using Monte Carlo simulations with the aim to reduce elevation overestimation in coastal wetlands at Plum Island, MA. We evaluated the performance of coastal wetland elevation refinement by using bare earth DEMs and DEMs created from the last return from the light detection and ranging (lidar) point cloud...

During the 2020–2021 summit eruption of Kīlauea volcano, Island of Hawaiʻi, staff at the U.S. Geological Survey Hawaiian Volcano Observatory (HVO) conducted 17 helicopter overflights of the eruption area between the dates of 21 December 2020 and 8 June 2021. Images captured during these flights were processed using the structure-from-motion (SfM) photogrammetry technique to produce...

Synthetic earthquake deformation was imposed on high resolution (~0.5 m/pixel)orthoimagery and digital elevation models (DEMs) for two regions of the Garlock fault in the east and west. This repository contains the input and result rasters for the analysis, further described in Hanagan et al. (2025): "Effect of land cover type on 3D deformation recovery from synthetically deformed high...

This U.S. Geological Survey (USGS) Data Release provides a digital geospatial database for the Bedrock geology of the Evitts Creek and Patterson Creek quadrangles, Maryland, Pennsylvania, and West Virginia from the original map of de Witt and Colton, 1964. Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent...

This U.S. Geological Survey (USGS) Data Release provides a digital geospatial database for the bedrock geologic map of the Beans Cove and Hyndman quadrangles and part of the Fairhope quadrangle (de Witt, 1974). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map as published in the...

Paleogeologic information directly above (supracrop) and below (subcrop) geologic periods from U.S. Geological Survey (USGS) reports was digitized from scanned plates. Geologic periods maps include the Jurassic (McKee and Others, 1956), Triassic (McKee and Others, 1959), Permian (McKee and McKee, 1967), Pennsylvanian (McKee and Crosby, 1975), and Mississippian (Craig and Connor, 1979)...

Information of hydrogeologic and geologic importance from the U.S. Geological Survey Oil and Gas Investigations Map 10, "Maps showing thickness and general character of the Cretaceous deposits in the western interior of the United States" (Reeside, 1944) were digitized from scanned maps 1, 2, 9, and 10. Isopach contours were captured and, along with Geologic Map of North America (GMNA)...

Important hydrological and geotechnical information from U.S. Geological Survey (USGS) reports detailing selected paleotectonic geologic periods, including the Jurassic (McKee and others, 1956), Triassic (McKee and others, 1959), Permian (McKee and McKee, 1967), Pennsylvanian (McKee and Crosby, 1975), and Mississippian (Craig and Connor, 1979), were digitized from scanned plates...
