Understanding the Japan Earthquake and Tsunami
Using maps and graphics, Smithsonian geologist Dr. Liz Cottrell provides an overview of the major earthquake and tsunami that struck Japan on March 11, 2011—one of the largest ever recorded globally. She explains the Pacific “Ring of Fire,” the movement of tectonic plates and subduction, the concept of earthquake magnitude, and the formation of tsunamis. Dr. Cottrell is also director of the Global Volcanism Program at the Smithsonian’s National Museum of Natural History.

Global System Tracks Tsunamis
In tsunamis, early warning systems are key to saving lives. NOAA uses buoys like these in a real-time global monitoring system called DART. The network of sensors, buoys, and satellites provides data to forecast and track tsunamis before they reach shore. Watch this video to learn more about the science behind tsunami tracking.

Tsunami Survival Guide
While tsunamis can neither be prevented nor precisely predicted, people educated about particular warning signs can save their own lives and the lives of others. In this interactive Web site, learn about tsunamis, related scientific research, and tips on how to prepare and survive a tsunami. "Tsunami: An Interactive Guide That Could Save Your Life" was developed by the Woods Hole Oceanographic Insitution (WHOI).

What is a Tsunami? A Smithsonian Scientist Explains the Japan Earthquake and Tsunami
Tsunamis, giant waves caused by underwater earthquakes, speed across the ocean at 400 miles per hour. Early warning systems, such as NOAA’s DART systems, are key to saving lives. Today, 47 DART stations are positioned all around the world ready to detect and warn coastal communities about the next potential tsunami.

Wave Size and Depth
Students investigate the relationship between the size of the wave and depth to which the effects of its energy can be observed. For more information: http://secoora.org and http://secoora.org/classroom/virtual_wave/wave_size_depth .

Mangroves at the Sea’s Edge
From the water, red mangroves appear to form an impenetrable tangle of roots, trunks, and leaves—a protective barrier against storms and tsunamis. More about mangroves can be found in our Mangroves featured story.
