A tsunami is a string of large ocean waves. Some people call it a “wave train" or a "tidal wave." Tsunamis, unlike normal ocean waves, are not caused by tides. The word tsunami comes from the Japanese. Tsunamis are caused by a sudden, large motion on the ocean floor. They can be caused by an earthquake under the ocean. Sometimes an underwater landslide or volcano is the cause. When one of these things happens, the energy passes through the ocean water. Just like the ripples from a rock being thrown into a pond, the energy released by one of these motions spreads out in all directions.

The energy can travel many miles away. Tsunamis move at high speeds. Most tsunamis happen in the Pacific Ocean. In the deep waters, a tsunami may travel 450 miles per hour. Out in the ocean, a tsunami may be hard to see. As it comes close to shore, its speed slows down. The height of the wave builds. The tsunami may suddenly rise into a wave ten to one hundred feet high. These large waves are a disaster for coastal regions and people living there. Tsunami warning networks alert people living along coastlines in the Pacific Ocean. When a warning is sounded, people can move away from the coast to higher ground. The wavelength can be as long as 150 miles. This means the time (wave period) between the giant waves is long, too. Giant waves on shore can last for hours or even days after the earthquake or other disturbance.

At the top of the list of the costliest natural disasters in the history of the United States is Hurricane Katrina. Hurricane Katrina was the third strongest hurricane ever to hit the U. S. It affected 90,000 square miles in Louisiana, Mississippi, Florida, and Alabama.

The hurricane formed over the Bahamas and turned into a Category 1 hurricane by the time it hit the southeastern tip of Florida. It got stronger as it traveled across the Gulf of Mexico. It made its second landfall off the coast of southeast Louisiana on Monday, August 29, 2005. It had become a category 4 hurricane by then. The storm surge that followed caused destruction from central Florida to Texas. New Orleans, Louisiana, experienced even more damage because its levees were breeched, letting water flood a large portion of the city.

The National Weather Service warned people of the tropical monster that was heading towards the southern coast. Residents were told to expect power outages. They were told they might lose their rooftops and to expect water shortages. The National Hurricane Director was very concerned. He personally called the governors of Louisiana and Mississippi. He even called President Bush at his ranch in Texas. He spoke directly with New Orleans mayor Ray Nagin. Nagin issued an evacuation order for his city. Most people left. About eighty percent of the population evacuated. The estimate was that around 100,000 people remained in the metro area. Some were stranded tourists; others did not own a car and had no way out. Those who were not able to leave were instructed to go to the New Orleans Convention Center and the Superdome.
