The Nevada Bureau of Mines and Geology's MyHAZARDS web app provides information on earthquakes, floods, fires, and other natural hazards in interactive map form. The map covers all of Nevada, as well as portions of surrounding states for certain datasets. The map includes:

The U.S. Geological Survey's Coastal Change Hazards Portal provides an interactive map showing the hazards posed to U.S. coasts from extreme storms, shoreline change, and sea-level rise. The map includes:

The U.S. Geological Survey's Produced Waters app provides information on over 100,000 samples of produced water from the oil and gas industry, waters extracted from hydrothermal systems (geothermal water), and some additional water wells.

The Marine Cadastre National Viewer is a joint product of the U.S. Bureau of Ocean Energy Management (BOEM) and the National Oceanic and Atmospheric Administration (NOAA). The viewer contains an enormous amount of information relevant to marine and coastal issues in interactive map form. Over 275 different map layers are available on a wide range of topics. The geoscience-related layers include:

The U.S. Geological Survey's Latest Earthquakes viewer shows the locations and magnitudes of recent earthquakes around the world. Users can also search the archives for global earthquakes dating back to the early 20th century. Maps can be generated for specified ranges of time, area, and earthquake magnitude.

Additional layers on the map include plate boundaries, major U.S. faults, and the USGS earthquake hazard forecast map for the United States.

The Nebraska Department of Natural Resources provides information about dams in the state in interactive map form. The map shows all dams more than 25 feet high or with a maximum storage capacity greater than 50 acre-feet.

Dams are color-coded according to the potential hazard they pose, with symbols designating existing dams, breached dams, and dams under construction. Specifications are available for each dam, including height, storage capacity, maximum discharge, surface area, and drainage area.
