Fundamental Science Practices
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
USGS provides unbiased, objective, and impartial scientific information upon which our audiences, including resource managers, planners, and other entities, rely.
Our programs produce accurate geologic maps and 3-D geologic frameworks that provide critical data for sustaining and improving the quality of life and economic vitality of the Nation. They also organize, maintain, and publish the geospatial baseline of the Nation's topography, natural landscape, built environment and more.

Earthquakes at Mauna Loa from June 2013 to June 2015 Earthquakes at Mauna Loa from June 2013 to June 2015
Earthquakes at Mauna Loa from June 2013 to June 2015. Green circles are 0-5 km (0-3 mi) deep and similar to ones prior to 1975 and 1984 eruptions, but cluster of 5-10 km (3-6 mi) deep quakes missing.

July 13, 2017—New map reveals geologic history: Mauna Loa Volcano's NE flank July 13, 2017—New map reveals geologic history: Mauna Loa Volcano's NE flank
"Geologic map of the northeast flank of Mauna Loa volcano, Island of Hawai‘i," published by the U.S. Geological Survey in May 2017, shows the distribution of lava flows and other deposits covering an area from Pu‘u‘Ula‘ula ("Red Hill") on the southwest to Hilo on the northeast.

Close up of Sheet 2 of "Lava inundation zone maps for Mauna Loa, Island of Hawai‘i," recently published by the U.S. Geological Survey. Colors depict lava Inundation zones for the Kaumana, Waiākea, and Volcano-Mountain View regions on Mauna Loa.
Surficial materials of Massachusetts—A 1:24,000-scale geologic map database Surficial materials of Massachusetts—A 1:24,000-scale geologic map database
The surficial materials geologic map database defines the distribution of nonlithified earth materials at the land surface in the 189 7.5-minute, 1:24,000-scale quadrangles that cover the Commonwealth of Massachusetts (index map). Across the State, these materials range in thickness from a few feet to more than 500 feet (ft). In some places, surficial materials are absent where bedrock...
Streamflow distribution maps for the Cannon River drainage basin, southeast Minnesota, and the St. Louis River drainage basin, northeast Minnesota Streamflow distribution maps for the Cannon River drainage basin, southeast Minnesota, and the St. Louis River drainage basin, northeast Minnesota
Streamflow distribution maps for the Cannon River and St. Louis River drainage basins were developed by the U.S. Geological Survey, in cooperation with the Legislative-Citizen Commission on Minnesota Resources, to illustrate relative and cumulative streamflow distributions. The Cannon River was selected to provide baseline data to assess the effects of potential surficial sand mining...
Surficial geologic map of Berrien County, Michigan, and the adjacent offshore area of Lake Michigan Surficial geologic map of Berrien County, Michigan, and the adjacent offshore area of Lake Michigan
The surficial geologic map of Berrien County, southwestern Michigan (sheet 1), shows the distribution of glacial and postglacial deposits at the land surface and in the adjacent offshore area of Lake Michigan. The geologic map differentiates surficial materials of Quaternary age on the basis of their lithologic characteristics, stratigraphic relationships, and age. Drill-hole information...

Regional water table (2016) in the Mojave River and Morongo groundwater basins, southwestern Mojave Desert, California Regional water table (2016) in the Mojave River and Morongo groundwater basins, southwestern Mojave Desert, California
From January to April 2016, the U.S. Geological Survey (USGS), the Mojave Water Agency, and other local water districts made approximately 1,200 water-level measurements in about 645 wells located within 15 separate groundwater basins, collectively referred to as the Mojave River and Morongo groundwater basins. These data document recent conditions and, when compared with older data...
