Two studies published Monday in the Bulletin of the Seismological Society of America show that seismic waves would be amplified as they pass through the Georgia Basin, the deposit of softer sedimentary rock that lies partly beneath Metro Vancouver. The findings have officials assessing the earthquake readiness of infrastructure throughout the region. That amplification could make the ground shake three to four times harder that it would in a different region. The researchers ran eight separate scenarios and found that a major quake near Metro Vancouver would most likely register a seven on the Modified Mercalli scale, which measures earthquake intensity on a scale of 1 to 12. The damage to well-designed buildings in the area would be negligible in an earthquake of that intensity, while older structures would be hit hard, according to the U.S. Geological Survey. But a different region standing on solid ground would experience an earthquake of the same magnitude as just five on the scale, meaning dishes and windows could break and pendulum clocks may stop. "The shaking in (Metro) Vancouver would be greater because of the presence of the Georgia Basin, especially when the earthquake occurred to the south or southwest," says lead author Sheri Molnar, with the University of B.C.'s civil engineering department. She said the waves would spread outward from the earthquake and would have to cross the deep southeast portion of the basin before hitting Vancouver. That would tend to cause the greatest increase in motion.

Shaking news.
Haven't we known this for a long time? I remember back in highschool a physics teacher talking about it, I'm fairly sure everyone's just hoping that it just doesn't happen in their life time here
I'm a little shaken by this news, its causing my tremors to flare up. I have family there, who might be a little perturbed by this. I bet this will leave people quaking in their boots for a few days, but I doubt this story will have any aftershock, instead replaced with news of a shakeup of some movies cast or something a little less groundbreaking.

FUUUU every time I hear Vancouver in sensationalist headlines I think its Vancouver Washington my town not Vancouver Canada. :<
p. sure the resulting tsunami would be pretty bad too

breaking news: big cities at most risk in the event of a natural disaster
[QUOTE=viperfan7;43617299]fuck did I miss one?[/QUOTE] I'm fissure you didn't. Also people here in bc are told straight up that there will be an earthquake eventually and I, for example, am just waiting for it any time. If vancouver island moves at all like they predict it will I want to be here with a video camera to ride it like a mega surfboard.
If an earthquake DOES hit, those towers are so fucked. I believe in Japan they have columns in the middle that act as shock-absorbers to minimize earthquake damage, so maybe they should implement similar columns just in case. Also, I think that if you instead build your tall structures to be like pyramids, I'd guess that the thicker bottom thinner top strategy would have similar shock-absorbant qualities, since there is more at the bottom to absorb seismic energy and the top will have a stronger base so that it doesn't get shaken to bits with as much ferocity. So basically we fucked up with our desire to build towers when we shoulda built modernized pyramids instead.
I live on Vancouver Island, which is its own little tiny continental plate sitting on the boundary zone between the North American plate and the Pacific plate being subducted beneath it. Depending on who you talk to, the BC coast is either 20 years overdue, or due anytime in the next 80 years, for a giant quake that'll lay waste to shit as bad or worse than the 1989 San Francisco quake. (The one that toppled fucking elevated freeways.) Vancouver Island is projected to [B]rise[/B] as much as five feet when the slip fault lets go. That's not going to go smoothly along the waterfront anywhere populated. The same faultline that's known as the San Andreas fault further south is roughly 300km offshore, so at least it's not directly beneath us. This is the baseline lurking horror that all coastal BC residents live with at all times. It's remarkeably easy to rationalize as long as you don't think about the fact that earthquakes are, for all intents and purposes, entirely unpredictable and random in their occurrence. I've been woken up in bed by minor quakes twice.
[QUOTE=The golden;43619968]Depends on the direction it approaches and the distance it forms. It'll most likely hit Vancouver Island first.[/QUOTE] If the tsunami comes in from the Pacific, Tofino and Uclulet get fucked hard in the face, and some native reservations are going to get fucked up as well, and it's going to be an exciting time up in Port Alberni when the wave rides up that inlet, but all in all, a tsunami from the Pacific isn't that scary for the inner coast ([B]I think[/B]). Anything built up on the southern edge of the island might get fucked up as well when the wave wraps around, but it'll get disrupted by the border islands and the big curve around, so I'd imagine that downtown Vancouver will more have to deal with an unusually fast and high "tide" from the incoming swell than it'll be facing Fukushima-quake style tsunami overwash fucking everything on Granville St. to hell. Note: I am not a hydrophysicist, I am a random fuck on the net.
Last I checked we don't really build for earthquakes in most of Canada because they don't happen that often. I'm pretty sure just about anywhere in Canada would be fucked if there was a major earthquake.

I'm pretty sure just about anywhere in Canada would be fucked if there was a major earthquake.[/QUOTE] The difference is that Vancouver is built on the Ring of Fire, and seismologists have known since at least the 80s (because I was alive to personally witness this; likely a decade or two before) that the area is seismically active. It's also been known since the late 80s or even further back, again, that the geological record shows massive earthquakes every 300-400 years from the Pacific-North American subduction slip fault. So, the architects and engineers should know better. You can be forgiven for not predicting lots of earthquakes when you build your town on top of the Canadian Shield, but this is kind of a known quantity out here.

Last time I was in Vancouver was last April, and it was 4/20 weekend so nyaahh. :downs: I seriously remember Vancouver buses primarily by their "how efficiently can this get me to the ferry/downtown" factor, because I'm usually on my way home and trying to hit a given ferry sailing. :v: I'm more worried about what's going to happen to Delta. What do you think will happen if the harmonic frequency of sand is hit for even a couple seconds during the Big One?
I KNEW it was a good decision not to go to vancouver film school

Fuck. Well at least I live on the border of Langley/Surrey.
Lest we forget Washington state, last I checked their building codes don't have any earthquake related safety measures anywhere near Vancouver's.

I know my high school had rooms above the staircases, which was later banned as a smoke hazard during a fire, but they never tore the rooms down, they used them for storage and the yearbook committee instead.
Eh, I have a friend in Alberta that said he'd let me crash if my house fell to the center of the earth Might be tricky getting there without a car, but it's a goal.
Hell, half the houses in the city still use knob & tube wiring, which hasn't been up to code in decades, and requires replacement to be able to get house insurance. Muh Automerge...
