00:00Scientists are warning that a mega tsunami with waves up to 1,000 feet tall could threaten three regions of
00:06the U.S.
00:07Virginia Tech researchers found that a powerful earthquake, combined with rising sea levels along the Cascadia subduction zone,
00:14could unleash this wave, hitting northern California, northern Oregon, and southern Washington hardest.
00:20That fault line runs from northern Vancouver Island to Cape Mendocino, California,
00:24and experts say there is a 15% chance of a magnitude 8.0 or greater earthquake within the next
00:3150 years,
00:32an event that could sink coastal land by up to 6.5 feet.
00:36Alaska and Hawaii face their own mega tsunami risks, too.
00:40Hawaii's volcanic islands have a history of them.
00:42A 1,000-foot wave crashed into Lanai about 105,000 years ago after a volcanic collapse.
00:49Lead researcher Tina Dura says Cascadia's communities sit right in the zone of subsidence.
