Brent Ward, an earth scientist at Simon Fraser University, said the earthquake was the second largest to hit the country since 1949, when another earthquake was recorded in the same area with a magnitude of 8.1.
"It's an earthquake in an area that gets a lot of earthquakes," he said. "It's a tectonically active area."
Ward said the area is known as the Queen Charlotte fault, where the earth's plates slide horizontally across each other in a strike-slip action, similar to what happens along California's San Andreas fault.
......
Ward said he wasn't surprised the tsunami warning was shortlived because the strike-slip movement along the fault doesn't generally trigger tsunamis.
"To trigger a tsunami you need to have a vertical movement of the sea floor, and it's that vertical movement that displaces water and triggers the tsunami," he said. "Because it's sliding across each other, you're not generally moving the water."

This research complements a huge body of research conducted in Washington, which has revealed that in the year 1700, it's likely the entire Cascadia Subduction Zone slipped, generating a massive, magnitude-9.0 earthquake, which sent a damaging tsunami across the ocean as far as Japan.
Much of the evidence suggests that these colossal earthquakes happen approximately 500 years apart. However, even smaller, more local earthquakes indicated by Valentine's and other's studies could cause widespread damage in California.
"Even if you don't have a 9 or an 8, it can still be very devastating to the region," he said.

He said that on average, the Cascadia ruptures roughly every 500 years, but the intervals between quakes can be as brief as 200 years or longer than 1,000.
Most recent data suggest there's about a one-in-10 chance the Cascadia will rupture in the next 50 years.
"One could happen here tomorrow, or it may take centuries for the next one to happen," Atwater said. "But you want to be prepared for it when it does."
........
.........
According to Chris Goldfinger, a professor in OSU’s College of Earth, Ocean, and Atmospheric Sciences and lead author of the study, the southern margin of Cascadia has a much higher recurrence level for major earthquakes than the northern end and it is overdue for a rupture. However, that doesn’t mean that an earthquake couldn’t strike first along the northern half, from Newport, Oregon, to Vancouver Island. Major earthquakes tend to strike more frequently along the southern end – every 240 years or so – and it has been longer than that since it last happened. The probability for an earthquake on the southern part of the fault is more than double that of the northern end.

(CNN) -- A tsunami warning for Hawaii, triggered by a powerful earthquake in Canada, proved nothing more than a pre-Halloween scare for thousands of people this weekend.
"The tourists are doing their best Chicken Little impressions," one CNN iReporter in West Maui, Hawaii, wrote early Sunday.
Sirens announced the tsunami warning across Hawaii on Saturday night, as thousands of revelers packed streets in Honolulu for the annual Hallowbaloo festival and many others in costumes headed to Halloween parties.
Restaurants, clubs and the festival immediately shut down and the parties turned into bumper-to-bumper traffic jams as residents headed to higher ground.
Visions of the devastating quake and tsunami that killed thousands in Japan in March 2011 fueled the fright, but the waves proved to be smaller and less powerful than feared.
While the warning said waves could surge between 3 and 6 feet, the largest wave, measured in Kahului on the island of Maui, was about 2.5 feet above ambient sea level, according to Gerard Fryer, senior geophysicist at the Pacific Tsunami Warning Center.

I made this prediction on a previous earthquake thread on October 6th. No one really listened to me or took me seriously. I saw this coming and I'm telling you this is not the end. This is just the initial jolt. I will predict here now that a much bigger event is going to occur very soon in this same general region or farther south closer to Vancouver Island.edit on 28-10-2012 by mark1167 because: typo

My brother lives in Vancouver.... I hope he uses his fat wife as a flotation device... hahahaha
Are you sure your brothers frst wife didn't cause the quake?
