Tsunami Warning Systems describes the processes involved in anticipating, detecting, and warning for a tsunami by summarizing data collection, modeling, analysis, and alert procedures used at NOAA's Tsunami Warning Centers. A simulated event and past tsunami occurrences are used to highlight warning system processes for determining the tsunami threat based on seismic and sea level data and tsunami ... Full description.

This interactive from NOVA Online shows how the 2004 Indian Ocean tsunami was triggered, how its waves traveled thousands of kilometers largely unchanged, and what happened once the waves reached coastlines both near and far from their source. Users can click on highlighted points on the map to see animations and written narrative describing the tsunami's effects. Full description.

This lesson plan is part of the DiscoverySchool.com lesson plan library for grades 6-8. It focuses on tsunamis and the destruction they can cause. Students design experiments to view the two types of tsunamis (fjord and ocean) and view the different wave patterns associated with each. Included are objectives, materials, procedures, discussion questions, evaluation ideas, and vocabulary. There are ... Full description.

This data tip describes the science behind the tsunamis caused by the great earthquake of December 26, 2004, which caused catastrophic damage and loss of life throughout the Indian Ocean basin. The discussion centers on how tsunamis are generated and how great quakes and resulting tsunamis occur at subducting plate boundaries. Links to more detailed information are embedded in the text. An exercise ... Full description.

In this activity, students study seismograms from three different seismic stations that recorded the magnitude 9.0 Sumatra earthquake of December 26, 2004. By comparing the arrival times of the P and S waves on each seismogram, they can determine the distance from the epicenter to each station and accurately map its location. Using this information, they also calculate the position of the quake-generated ... Full description.

This site is the homepage of the National Oceanic and Atmospheric Administration's (NOAA) tsunami warning center for Alaska and the west coast of the United States. Users can access current current tsunami information through an interactive map that shows the latest events and information statements. Rolling over the map symbols provides the date and time, location, and preliminary magnitude of earthquakes. ... Full description.
