Monster tsunami

Evidence of a ‘monster tsunami’ has been found in Hawaii, and it could happen again

Evidence of an unprecedented tsunami found inside a sinkhole on Kaua’i had previously been documented in 2001. So researchers in Hawaii set out to recreate in models an event that could have led to the flooding of that particular sinkhole on Hawaii.

What they found was that the geometry of the eastern Aleutian islands in Alaska is particularly arranged to produce a monster tsunami pointed directly at the island of Kaua’i. In the tsunami models, water levels on shore reached 26 to 30 feet — more than enough water to top the sinkhole.
