Interactive map of thermal springs in the United States

The National Oceanic and Atmospheric Administration's thermal springs map displays the location and temperature of thermal springs throughout the U.S. The hot springs shown on the map are color-coded based on recorded temperature (red = boiling, orange = hot, yellow = warm, black = information not available). Users can click on individual hot spring locations to find the hot spring name, location, and most recently recorded temperature.

Interactive map of drought conditions across the United States

The U.S. Geological Survey's WaterWatch program maps below-normal 7-day average streamflow, identified through comparison to historical streamflow readings, to produce their DroughtWatch map. The map identifies drought conditions ranging from extreme hydrological droughts to below normal streamflow conditions across the entire U.S.

Interactive map of volcanoes and current volcanic activity alerts in the United States

The U.S. Geological Survey's Volcanoes and Current Activity Alerts map shows the location and activity levels of all volcanoes in the United States. The map allows for filtering based on both location and current volcano status. Each volcano is depicted by a small colored triangle with different colors indicating various volcano alert levels:

  • Green = normal
  • Yellow = advisory
  • Orange = watch
  • Red = warning

Users can click on individual volcanoes to see that volcano's page on the USGS website.

Map of geothermal power generation in each state

The National Renewable Energy Laboratory's (NREL) map of current and planned geothermal power production by state shows the nameplate capacity, the maximum manufacturer-rated output of a generator in megawatts, for geothermal energy in each state as of February 2015 (for more detailed and up-to-date information on geothermal energy development in the U.S., visit NREL's Geothermal Prospector web app). The numbers in white show the current installed capacity, while the numbers in yellow show the planned additions.
