A tsunami is defined as a series of ocean waves that are generated by large movements or disturbances on the ocean's floor. The causes of these disturbances include volcanic eruptions, landslides, and underwater explosions. Earthquakes, however, are the most common cause. Tsunamis can occur close to the shore or travel thousands of miles if the disturbance occurs in the deep ocean. Where ever they occur, though, they often have devastating consequences for the areas in which they hit.



For example, on March 11, 2011, Japan was struck by a magnitude 9.0 earthquake that was centered in the ocean 80 miles (130 km) east of the city of Sendai. The earthquake was so large that it triggered a massive tsunami that devastated Sendai and the surrounding area. The earthquake also caused smaller tsunamis to travel across much of the Pacific Ocean and cause damage in places like Hawaii and the west coast of the United States. Thousands were killed as a result of both the earthquake and tsunami and much more were displaced.

Unfortunately, large tsunamis such as the one that struck Japan are not uncommon. In addition, while thousands were killed in Japan because of the twin disasters, the March 2011 tsunami is not the world's deadliest. Throughout history, there have been many earthquakes, volcanic eruptions and other disturbances that have caused very large tsunamis that have killed hundreds of thousands of people.
