The Cascadia Subduction Zone is a sleeping monster lurking just off the Northwest coast of the United States. It extends 600 miles between Northern California and Vancouver B.C. and experiences a massive megathrust earthquake every 250 years on average. The last one happened 321 years ago and scientists say there is a 30% chance we’ll see another in the next 50 years. It’s expected to rival the 9.0 quake that shook Japan for 6 minutes, which was the most destructive natural disaster in human history. It unleashed a tsunami that reached 100 feet in some areas, caused an estimated $360 billion in damages and claimed some 16,000 lives.

If this sounds ominous, that’s because it is. As catastrophic as the Tohoku quake was, Japan is light years ahead of the United States when it comes to earthquake preparedness. This grim reality has many experts very worried. And in this episode of Weathered we spoke with some of them about what we can expect when the “Big One” does hit, the kinds of work that need to be done to make our communities more resilient, and what you can do to keep yourself and your loved ones safe.

Weathered is a show hosted by meteorologist Maiya May and produced by Balance Media that helps explain the most common natural disasters, what causes them, how they’re changing, and what we can do to prepare.

  1. It's a good idea to do what we can do to prepare. How ever, if you think about tectonic plates, is there any way to know what they will do when they decide to shift on a scale beyond our imagination? Aren't they at least partly responsible for some mountain ranges? Well, wouldn't be one thing we could do to prepare for one that big. Not too surprising some folks are trying get to Mars. lol. Pretty sure I won't be one to go to Mars. I'd just have bend over and kiss my a** goodbye.

  2. If you want to skip the misinformation (fake news?) and get the facts about this, look up some Nick Zentner videos. But I'll warn ya… You might learn something!

  3. If a major earth quake erupted in cascadia or when California falls into the sea it would be devastating

    Setting off Yellowstone who's ask will cover most of Northa american possibly entire world

  4. I’m in Tacoma and problem is most people don’t understand if it happens you are not going to be driving anywhere. To many bridges and raised roads here. I have a bug out bag in my trunk just in case.

  5. Magnitude 9? lol she's crazy if she doesn't think it will be a 10 or worse. Yes folks, there is a "worse". Stop buying real estate in California and Oregon!
    I guess it depends on the Juan De Fuca plate.

  6. This video has really similar vibes to the Onion Video "Memorial honors victims of imminent dam disaster" v=yjfrJzdx7DA
    "This disaster will have been preventable, all of the warning signs are here now. Yet, no one will have done anything about it."

  7. Hawaii will have a rough time, too. Joint Base Pearl Harbor/Hickam, Kaneohe MCAS, Barber's Point NAS, other military bases and almost all the population will be hammered. Me, for example.

  8. A mega quake could be decades away.
    A more imminent threat is a mega flood.
    The West is several decades overdue for one. It's not a matter of if, only a matter of when. With property damage approaching a trillion Dollars, the resulting "cataclysm" will be unprecedented in US history. Depending on the storm track, Northern California's system of levies will almost certainly fail, potentially transforming the entire Central (Sacramento) Valley into a "great inland sea" nearly 50 miles wide and several hundred miles long. It will begin suddenly, with very little warning. Here's the most likely scenario; During any given rainy season, beginning in October/November, cold, powerful winter storms develop over the gulf of Alaska and track south, southeast along the coast, one after another, moving inland and dumping up to 100' of snow in the high Sierra. January comes along and the storm track shifts southerly. A relentless (tropical) atmospheric river or "Pineapple Express" dumps the equivalent volume of 40-50 Mississippi rivers on California by February, melting the (lower elevation) mountain snowpack in the process. The resulting deluge is Biblical in scope. The city of Sacramento, along with all of it's suburbs, become inundated with 10' – 15' of flood water. With each passing year the odds of a mega flood increases and global warming is accelerating the time-frame.

  9. More obviously bad ideas, and ALWAYS positioned to DESTROY the most beautiful geographic areas in the World. Radioactive waste already flows out in the Columbia River from Hanford, right? And yet the bass holes and their institutions who have set this up continue to lie and be unaccountable?

  10. America ? Or just the north west . Americas a pretty big place. I mean Portland might be wrecked but Cleveland? Baltimore?……
    Yeah they’re already wrecked I guess it’s a moot point

  11. Hopefully it hits soon. I'd like to see that 9.0 and a 200' title wave being stopped by the rockies. Wash all that west coast garbage out to sea.

  12. I love how they're building everything up to earthquake standards… I just sure hope it could also withstand the tsunami
