00:00What if a 1,000-foot wall of water came crashing down on America,
00:04with just minutes to escape?
00:06Scientists are sounding the alarm over a terrifying threat,
00:09a mega-tsunami so powerful it could wipe entire cities off the map.
00:14And it all starts with one fault line, the Cascadia subduction zone.
00:18Running from northern Vancouver Island to northern California,
00:21this zone could unleash a magnitude 8.0 earthquake within the next 50 years.
00:26The odds? 15%.
00:28But the potential impact? Devastating.
00:31If it hits, Seattle, Portland, and entire stretches of the West Coast could sink by over 6 feet.
00:36Then comes the wave.
00:38Not your typical tsunami, but a 1,000-foot mega-tsunami.
00:42It would dwarf buildings, erase coastlines, and leave no time to react.
00:46Even Alaska and Hawaii, though farther away,
00:49are still in danger due to their seismic vulnerability.
00:52And here's the scariest part.
00:54There hasn't been a quake on this fault since the year 1700.
00:57Which means, it's overdue.
01:00Recovery? It could take decades.
01:02Preparation? It starts now.
01:04Because when nature strikes at this scale, there are no second chances.
01:08And the first chances?
01:09The chances are that we could stand around and wonder the lobe,
01:10and instead ofosaurus and lorujemy on this side and above that line,
01:11which means that there are no two, you know,
01:12that has to be part of the new contamination.
01:13But you can't be warned.
01:14No matter where there is,
01:15we can't already know where you want to go.
01:16Not in the middle of the sea.
01:17But, when I'm trying to get rid of the little bit,
01:18I'm trying to get rid of the little sky.
01:19But ...
01:21How long do weábamos to get rid of the sun,
01:22the sun on the sides?
