This portal provides access to information on United States Geological Survey (USGS) research and resources on tsunamis and earthquakes. Materials include news and events in USGS tsunami research, an overview of the program, and basic information on the life of a tsunami. There are also links to individual research projects. The site also features an extensive set of tsunami animations of real and ... Full description.

This program of the Pacific Marine Environmental Laboratory seeks to mitigate tsunami hazards in Hawaii, California, Oregon, Washington, and Alaska. Research and development activities focus on an integrated approach to improving tsunami warning and mitigation. The website contains realtime and modeled data from several monitoring stations in the Pacific Ocean. Animated simulations illustrate the ... Full description.

Students investigate parts of ocean waves and their measurements. An on-line wave simulator allows then to study the effects of wave height, length and period on a boat's movements. Using records of tsunami waves, students compare these heights to familiar landmarks and test a hypothesis about possible relationships between wave height and ocean size and depth.

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.

The sudden movement of the Pacific tectonic plate under the North American plate caused a massive earthquake and a tsunami in Japan in 2011. This resource provides interactive maps illustrating the shifting plates and rising water, the shaking magnitude and subsequent tsunami wave heights. Additional interactive maps reflecting aftershocks, infrastructure impact and radiation levels throughout the ... Full description.

This lesson introduces students to electromagnetic waves, the concept of photons, and the relation between photon wavelength and energy. This is tied to solar observations at various wavelengths using the many types of electromagnetic waves. Students will discover that electromagnetic waves are a linked oscillation of magnetic fields and electric currents, spreading through space. They will also discover ... Full description.

This Why Files article looks at tsunamis in the wake of the July 17, 1998 disaster in Papua New Guinea that killed over a thousand people. Topics covered are: the causes of tsunamis, tsunami movement across the ocean, the history of some killer tsunamis of the last few hundred years, and ways to reduce human vulnerability to tsunamis. Readers can download a movie about how investigators think the ... Full description.

This text relates a scientific detective story through clues from both sides of the Pacific. In the year 1700, a mysterious tsunami flooded fields and washed away houses in Japan. It arrived without the warning that a nearby earthquake usually provides. Samurai, merchants, and villagers recorded the event, but nearly three centuries would pass before discoveries in North America revealed the tsunami's ... Full description.
