History of tsunamis on Oahu

Click to enlarge

Thirty-three tsunamis with flood elevations greater than 3.3 feet have made landfall in the Hawaiian Islands during recorded history, and 10 of these had significant damaging effects on Oahu - and 4 of those since 1946.

In the last 20 years development within the Oahu coastal zone has proliferated. If wave runups like those of the 1957 or 1960 tsunamis occurred today, there exists a high probability that low-lying coastal areas such as Waikiki, Waimanalo, Kaaawa, Punaluu, and Nanakuli would suffer damage.


Am I at risk?

If you live in a low-lying coastal area, you are at risk. All low-lying coastal areas can be struck by tsunami.
