The National Ocean and Atmospheric Administration's tsunami travel times map displays the estimated pre-computed tsunami travel times to select coastal locations from any point in the ocean. The tsunami travel times displayed are in hours and were calculated using TTT software. It is important to note that the travel times shown on the map are estimates and should be used general information only. In the event of an actual tsunami, please visit tsunami.gov for real-time tsunami information.

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.

The U.S. Geological Survey's WaterWatch Flood Map allows you to find areas currently experiencing flood and high flow conditions across the United States. The map is updated daily and provides the option to search flood conditions by state or water-resources region.
