sunamis can strike any coast. They can be generated in all of the world's oceans, inland seas, and in any large body of water. They have caused damage and deaths in coastal areas all around the world.This is the most volcanically and seismically active zone in the world. It extends from Chile, northward along the South American coast through Central America, Mexico, the West Coast of the United States, and the southern part of Alaska, through the Aleutian Islands to Japan, the Philippine Islands, New Guinea, the island groups of the Southwest Pacific, and to New Zealand.
An assessment of the tsunami hazard in the United States shows that while a tsunami can strike any U.S. coast, the hazard level varies. The hazard levels shown below are based largely on the historical record (through 2014), geological evidence, and location relative to tsunami sources, all of which provide clues to what might happen in the future.
