According to USGS scientists, the sea floor near the earthquake was uplifted several meters. The displacement of water above the sea floor triggered the tsunami , which caused catastrophic levels of destruction in countries around the Indian Ocean basin, reaching as far as the east coast of Africa.
In fact, the largest tsunami wave ever recorded broke on a cool July night in 1958 and only claimed five lives. A 1,720 foot tsunami towered over Lituya Bay , a quiet fjord in Alaska, after an earthquake rumbled 13 miles away.

Flooding can extend inland by 300 meters (~1000 feet) or more, covering large expanses of land with water and debris. Inundation distances can vary greatly along the shorelines, depending on the intensity of the tsunami waves, the undersea features, and the land topographic elevations.
Large tsunamis have occurred in the United States and will undoubtedly occur again.
