00:00What if a 1,000-foot tsunami slammed into the U.S. coastline?
00:04Sounds like a Hollywood movie, right?
00:06But scientists say it's not only possible, it's happened before.
00:10In 1958, a mega-tsunami in Alaska's Lituya Bay sent water surging 1,0720 feet up the shoreline.
00:17That's taller than the Empire State Building!
00:20Now experts warn, under the right conditions, it could happen again.
00:24A massive earthquake under the ocean.
00:26A sudden landslide into a narrow coastal bay.
00:29These rare combinations could trigger a wall of water taller than a skyscraper.
00:34And it's not just the West Coast.
00:36Even places like Texas have had powerful quakes.
00:39And geologists say the Cascadia subduction zone, running from California to Canada, is a ticking time bomb.
00:45If that fault slips, coastal towns could drop several feet in minutes.
00:49And if a landslide follows, we're talking about a mega-tsunami that could wipe out cities, roads, farms, and more.
00:56Emergency planners are already running simulations.
00:59Because the past has shown us, giant waves don't just belong in the movies.
01:03They can become reality.
