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.
