Study Indicates Potential for a 1,000-Foot Mega-Tsunami on the US West Coast

Buzzline

Research published in the Proceedings of the National Academy of Sciences suggests that a 1,000-foot mega-tsunami could feasibly impact the Pacific Northwest region. Findings by geoscientist Dr. Tiffany Dura from Virginia Tech and geophysicist Christopher Adams indicate that a significant rupture of the Cascadia subduction zone, coupled with a substantial underwater landslide, could generate a wave comparable to the 1,720-foot surge recorded in Lituya Bay, Alaska, in 1958. The risk area encompasses Northern California, Oregon, Washington, and extends to Canada, affecting millions of residents along the coastline.

00:00Scientists are warning that a 1,000-foot megatsunami is not outside the realm of possibility on America's west coast.

00:07Research published in the Proceedings of the National Academy of Sciences, led by geoscientist Dr. Tiffany Dura of Virginia Tech,

00:15found that a major rupture of the Cascadia subduction zone could trigger a massive wave if it combines with a

00:21large undersea landslide.

00:22The scientists point to the 1958 Lituya Bay, Alaska event, where a similar combination produced a wave 17-20 feet

00:30tall.

00:31As proof this kind of surge has happened before on American soil, the danger zone runs the entire Pacific Northwest

00:37coast,

00:37from northern California through Oregon and Washington and up into Canada, an area home to millions of Americans.

00:44Researchers stress the odds are low, but the physics say it is possible, and coastal communities should understand the risk.
