• Tsunamis are giant waves or rapid rises in sea level. They’re rare events, occurring on average about twice a year somewhere in the world — about once every 15 years for the most destructive tsunamis, which can cover an entire ocean basin.
• Tsunamis travel at speeds of up to 500 miles an hour in the open ocean and rise to heights of several hundred feet as they come ashore.
• They can cause widespread devastation in coastal areas — especially in the aftermath of a large earthquake.
