00:00Scientists are renewing urgent warnings about one of the most catastrophic threats facing the United States.
00:06A mega tsunami capable of generating 1,000-foot waves could obliterate the entire U.S. west coast within minutes
00:13of triggering.
00:14The Cascadia subduction zone is a 700-mile fault line running off the coasts of California, Oregon, and Washington.
00:22It has not produced a major earthquake in over 300 years.
00:26Geologists warn that this means the fault line is long overdue for a major rupture.
00:30When it finally breaks, the resulting megaquake, estimated at magnitude 9.0 or greater, could occur.
00:38That quake could trigger a massive tsunami wall.
00:42The tsunami could travel at speeds of up to 500 miles per hour across the Pacific.
00:47Coastal cities like Seattle, Portland, and San Francisco could be hit within 15 to 20 minutes.
00:53More than 30 million Americans live within the projected impact zone.
00:57Experts warn that evacuation routes in coastal Oregon and Washington are critically inadequate.
01:03For many residents, there may be no time to escape once the tsunami begins.
01:08Scientists are now calling for urgent federal investment in early warning systems.
01:13But so far, no comprehensive federal warning system has been built.
01:17For many residents, there may be no time to escape once the tsunami is built.
01:17For many residents of America are about to escape again.hold
