How big was the Japanese tsunami this year? Reseachers now say 132.5 feet, or 40 meters. Wow. That's the biggest tsunami ever to hit Japan, and bigger than the tsunami that devastated coastlines around Indonesia in 2004.
As if that's not big enough, the largest tsunami ever was 1,720 feet (524 meters), trigerred by a rock and ice fall in a small inlet in Alaska in 1958. Yikes. That's taller than the Empire State Building in New York.
