A powerful earthquake in Alaska sent towering waves up to 30 feet (9 meters) tall crashing down on Hawaii about 500 years ago, leaving behind fragments of coral, mollusk shells and coarse beach sand in a sinkhole located on the island of Kauai, new research finds.
The quake, likely a magnitude 9.0, sent the mighty waves toward Hawaii sometime between 1425 and 1665, the study found. It's possible that another large Alaskan earthquake could trigger a comparable tsunami on Hawaii's shores in the future, experts said.
The tsunami was at least three times the size of the damaging 1946 tsunami, which was driven by an 8.6-magnitude earthquake off the Aleutian Islands. Mammoth tsunamis, like the one described in the study, are rare, and likely happen once every thousand years. There's a 0.1 percent chance it could happen in any given year, the same probability that northeastern Japan had for the 9.0-magnitude 2011 Tohoku earthquake and related tsunami, said Gerald Fryer, a geophysicist at the pacific Tsunami Warning Center in Ewa Beach, Hawaii, who was not involved in the study.

yikes Hawaii is decades overdue for a big wave.
Thanks!
Sidebar — there was a landslide-induced tsunami in Alaska, Lituya Bay, in the late 1950s, which had eyewitnesses and even survivors — the debris line from that was over 1700 feet above sealevel.

wow!
I have seen at least two shows that included that tsunami. One was mostly about how they figured out what happened.
Probably on Discovery back in the late 1990’s or early 2000’s. Before they started airing a bunch of crap shows.
Definitely. That’s 1/3 of a mile.
A couple of the witnesses were a father and son who were camping and fishing and whatnot. An older couple they’d dined with the previous evening just vanished.

Thanks smokingfrog.
A few years ago there was a TV drama in Miami about a 30 foot tidal wave hitting caused by a big slide off the side of an island in the Azores. CSI Miami?
