Interactive database for geologic maps of the United States

The U.S. Geological Survey hosts the National Geologic Map Database (NGMDB). This interactive tool serves as a national archive for high-quality, standardized geologic maps created by the U.S. Geological Survey and state geological surveys.

The MapView section of the NGMDB displays geologic maps from across the country dating back to 1879. The database is searchable by address, and results can be narrowed further using scale and date filters.

Interactive database for topographic maps of the United States

The U.S. Geological Survey hosts topoView, an interactive database of the survey’s topographic maps.

The map is searchable by address, and clicking on any point on the map brings up topographic maps of the area dating back to 1879. Map results can be narrowed further using scale and date filters.

Clicking the “show” option will overlay the selected map onto the coordinates of topoView’s base map. Adjusting the map overlay transparency allows comparison of historical and present-day topography.

All maps in topoView are downloadable in multiple formats.

Interactive map of groundwater monitoring information in the United States

The National Ground-Water Monitoring Network compiles information from over 7,000 groundwater monitoring wells across the country, including Federal, State, and local groundwater monitoring networks. Although the image above only shows the contiguous United States, the interactive map also includes wells from Alaska, Hawaii, Puerto Rico, Guam, and the U.S. Virgin Islands.

Water as One Resource

This course provides an overview of how groundwater and surface water interact, what the implications of these interactions on water resources are, and how water can be more effectively managed if an understanding of these interactions is incorporated.

The course presenters are Ken Bradbury from the Wisconsin Geological and Natural History Survey, William A. Alley from the National Groundwater Association, and Thomas Harter from the University of California, Davis.

State Responses to Induced Earthquakes

The surge in recent years of earthquake activity associated with some oil and gas operations, most notably in Oklahoma, has spurred a range of actions and responses from state geoscientists and regulators. States have taken measures to monitor these earthquakes and moderate the activities that may be causing them, particularly the deep underground injection of large volumes of wastewater. Many states with extensive oil and gas operations but little or no increased earthquake activity have also adopted practices to prevent and prepare for potential induced earthquakes in their area.

Induced Seismicity in the Mid-Continent

This course provides information about induced seismic activity in the United States, specifically in the mid-continent. It includes information on mitigation planning, the state of seismic monitoring at the state level, and the challenges in communicating the science of the issue to the public and decision-makers.

The course presenters are Bill Ellsworth from the U.S. Geological Survey, Austin Holland from the Oklahoma Geological Survey, and Rex Buchanan from the Kansas Geological Survey.
