A major earthquake could hit the B.C. coast any day now or in hundreds of years, quake expert from Washington state says

WEST COAST - The Big One could hit the B.C. coast any day now or hundreds of years from now, says an earthquake expert from Washington state.
Major earthquakes registering about 9.0 on the Richter scale occur about every 500 years along the fault zone extending from mid-Vancouver Island to Northern California, geologist Tim Walsh told an emergency planning forum in Richmond.
The area, known as the Cascadia Subduction Zone, separates the Juan de Fuca and North American tectonic plates and is where the oceanic crust of the Pacific Ocean is pushed toward and beneath the continent at a rate of 40 millimetres per year -- the process that is called subduction.
The Cascadia subduction zone is a very long sloping fault that stretches from mid-Vancouver Island to northern California.
The last major subduction earthquake in the zone occurred in January, 1700 -- which means that a major earthquake is probable sometime between now and the next few hundred years, said Walsh, geologic hazards program manager of the Washington Department of Natural Resources.
Walsh said it is difficult to predict what impact a major earthquake would have on downtown Vancouver given that no modern city has been hit by a subduction earthquake.
"Certainly the Lower Mainland is a great distance from where the strongest ground-shaking would be," Walsh told reporters, after speaking to the Emergency Preparedness for Industry and Commerce Council forum.
Walsh said that a large subduction earthquake would cause a major tsunami and noted that the earthquake in 1700 generated a tsunami that travelled across the Pacific Ocean and hit Japan.

Walsh said such a tsunami could send a three- or four-metre surge down the Strait of Juan de Fuca.
Walsh said areas with water-saturated sands such as Richmond and other municipalities in the Fraser Delta basin would be much more susceptible to ground-shaking than areas with bedrock.
Vancouver International Airport and connecting bridges would be vulnerable, he said.
There was a similar sky-is-falling article like that in the Canada section - a month ago. I'm sure some of you remember that.

Cool, I can't wait to roast marshmellows over any open fissures or possible lava flows.

A giant tornado could hit Edmonton again any day or in a hundred years.
Hell - giant robot sharks with frickin' laser beams could also land their ships on the Leg Annex Building and use it as their hive! Any day! (one could only hope)
It's fear mongering. I'm sure the residents of Van are all very aware that the risks of a major Quake are there, and to prepare themselves for the worst. (one can only hope)
BTW - is there anything (besides insurance policies that may or may not respond...) the city has planned - as far as funds go - a disaster fund? I'm completely ignorant...
See Alberta has this "heritage fund" that will be there to provide the funds when the aforementioned sharkbots land.... or when the oilpatch dries up and we all need pogi.... etc.

Thunder Bay is prepared incase of a Tsunami! Council held an emergency session in 2005 AND had a 120,000$ study put into it!
We also have preparedness plans should terorrists fly a plane into the skyscrapers we don't have, or we should have a major earthquake along the fault lines we don't have.
Thunder Bay: If it won't happen, we're ready for it!
It may seem silly that every month or two they have an article saying that a earthquake may hit tommorrow or a hundred years from today. But, I can tell you that if a earthquake does hit, say next year, everyone who survives will complain that they didn't have any warning and the city and government weren't perpared for the emergency.

yup - they always do this when there is an earthquake anywhere in the world - telling us locals to expect it here...
my local (suburb) paper has an article on earthquake kits
they must just recylce the same article each time
do you have an earth quake kit? or some sorta kit incase of an emergency we all should have a kit of some sort you never know what will happen thats just part of life as they say in boy scouts be prepared!
its not a matter if one will happen its just a matter of when.......
