Has the US ever had a tsunami?

Large tsunamis have occurred in the United States and will undoubtedly occur again. Significant earthquakes around the Pacific rim have generated tsunamis that struck Hawaii, Alaska, and the U.S. west coast. … The most noteworthy tsunami resulted from the 1929 magnitude 7.3 Grand Banks earthquake near Newfoundland.

To help identify and predict the size of a tsunami, scientists look at the size and type of the underwater earthquake that precedes it. This is often the first information they receive, because seismic waves travel faster than tsunamis.

How far inland did the 2004 tsunami go?

In many places, the waves reached as far as 2 km (1.2 mi) inland. Because the 1,600 km (1,000 mi) fault affected by the earthquake was in a nearly north–south orientation, the greatest strength of the tsunami waves was in an east–west direction.
