What Will Happen When Cascadia Subduction Zone Slips

Noryungi writes: The New Yorker has published a chilling account of what would happen in the case of a major earthquake (roughly magnitude 9.0) inevitably striking the Cascadia subduction. "Under pressure from Juan de Fuca, the stuck edge of North America is bulging upward and compressing eastward, at the rate of, respectively, three to four millimetres and thirty to forty millimetres a year. It can do so for quite some time, because, as continent stuff goes, it is young, made of rock that is still relatively elastic. (Rocks, like us, get stiffer as they age.) But it cannot do so indefinitely." Most of the west coast of the U.S. and Canada is at risk, from Vancouver all the way down to Los Angeles and beyond. Most of the states and cities within this region are woefully under-prepared for a large earthquake. Scientists peg the odds at 1-in-3 for a quake within the next 50 years, and 1-in-10 for a really powerful one.

    There's also a problem with liquefaction. Most of Victoria and Vancouver (in BC) are built on soft earth which will become mud and will stop supporting the stuff we've built. All those foundations, bridges, streets, they'll all become impassable. There's a liquefaction map I saw at an engineering presentation and the whole thing was red and black. Victoria is literally built on landfill garbage right next to the ocean. One of its landmark buildings, the Empress Hotel, was slowly sinking until it had a major refurb to drive piles down as far as they could reach.

    Vancouver is the biggest port for exporting all of Canada's wheat, lumber, ore, etc. If it shuts down, people could be starving for work and food all over the world. It's not all bad though, because EA North would cease to exist. However, greater Vancouver is where most of BC's engineers live and work. We're your experts in fixing up after an earthquake, and most of us would probably be gone.

    It's going to be bad when it hits. The upside is that most people here have earthquake kits, emergency supplies, ninja reflexes (we do earthquake drills) and have some idea that it will in fact happen.
