A summary of the earthquake sequence in the Alaska Peninsula during 2020 and 2021. On 29 July 2021, a magnitude (M) 8.2 earthquake occurred southeast of Perryville, Alaska, (south of the Alaska Peninsula). This event was preceded in 2020 by two nearby earthquakes. The first was a M7.8 earthquake (22 July 2020), followed three months later by a M7.6 earthquake (19 October 2020).

The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center in Woods Hole, Massachusetts, is one of three centers serving the mission of the USGS Coastal/Marine Hazards and Resources Program (CMHRP). Since its authorization by Congress in 1962, the CMHRP has served as the primary Federal program for marine geology and physical science research.

The Coconino aquifer (C aquifer) supplies water to northeastern Arizona. Proposed increases in groundwater withdrawal to meet population demands, coupled with ongoing drought conditions, increase the potential for water-level changes in the aquifer. The USGS monitors groundwater and surface-water conditions in northeastern Arizona.

An interactive geonarrative with a plain-language summary of the four 2020 Intermountain West (IMW) earthquakes that occurred in Utah, Idaho, Nevada, and California.

Neural networks are powerful deep learning models that help us make accurate environmental predictions. This data visualization describes how to train an artificial neural network, and how the USGS uses them to make physically-realistic predictions with less data.

The USGS has been monitoring stream temperature in the Delaware River Basin since 1901, and has amassed over 650,000 daily temperature measurements. This data visualization story explores temporal and locational patterns in stream temperature observations, and how spatial variability and data gaps add complexity to prediction efforts.

This map shows the unvegetated and vegetated area of coastal wetlands and adjacent land (inland and shorelines) for the Conterminous United States computed from 2014-2018 Landsat imagery at ~30 meter horizontal resolution.

The USGS Mississippi Alluvial Plain (MAP) Regional Water Availability Study began airborne geophysical mapping to obtain high-resolution information about the hydrogeologic structure and properties of the aquifer. This geonarrative showcases the geophysical data collected in this effort and provides a three-dimensional view into the Mississippi Alluvial Plain subsurface.
