00:00Could a 1,000-foot tsunami crash into the U.S. West Coast?
00:03Scientists say it's not science fiction. It's a real possibility.
00:07There's a 15% chance that a massive magnitude 8.0 earthquake
00:11could strike the Cascadia subduction zone within the next 50 years.
00:15That's the dangerous fault line running 600 miles from Northern California to Vancouver Island.
00:20And if it ruptures, it could instantly drop coastal land by up to 6.5 feet.
00:25Then, unleash a tsunami hundreds of feet high.
00:29This mega tsunami could devastate millions of lives, destroy over 70,000 buildings,
00:34and cost $81 billion in damage.
00:37Southern Washington, Northern Oregon, and Northern California are at highest risk.
00:42Alaska and Hawaii face their own threats, too.
00:45Experts are urging governments to act now.
00:47That means tsunami evacuation plans, reinforced hospitals, and stronger infrastructure.
00:53The last mega quake hit in the year 1700.
00:56The next one could strike tomorrow.
00:58Are we ready for it?

01:04.
