Scientists Alert on Mega-Tsunami Threat to Three US Coastlines

Buzzline

Experts are reiterating their concerns regarding the danger of a mega-tsunami impacting three US coastal regions — the Pacific Northwest, Alaska, and Hawaii. Recent geological simulations indicate that the Cascadia Subduction Zone is overdue for a 9.0 magnitude earthquake that could unleash 100-foot waves on Oregon and Washington in a matter of minutes. The melting glaciers in Alaska heighten the likelihood of underwater landslides that could produce 1,000-foot waves in sheltered bays, while Hawaii faces the risk of Pacific Rim tsunamis with less than 20 minutes of advance warning.

00:00Scientists are issuing a renewed warning about one of America's most devastating and under-discussed threats—the mega-tsunami.

00:07New modeling from leading geological research institutions shows that three distinct U.S. coastlines face catastrophic tsunami risk—the Pacific Northwest,

00:18Hawaii, and Alaska.

00:20The Cascadia subduction zone—a 700-mile fault off the Oregon and Washington coast—is overdue for a magnitude 9.0 earthquake.

00:30Scientists say it could trigger waves up to 100 feet high, and those waves could strike the coast within minutes.

00:36In Alaska, underwater landslides triggered by glacial retreat could produce waves exceeding 1,000 feet, similar to the terrifying 1958

00:46Lituya Bay megawave.

00:47Hawaii sits at the center of a Pacific Rim network, where any major undersea earthquake could send waves crashing into

00:54Honolulu in under 20 minutes.

00:56Scientists say the U.S. has not invested enough in early warning infrastructure for disasters on this scale.

01:04Researchers warn the question is not whether these events will occur. It is whether America will be ready when they
