More details to follow.
An unusually large swarm of tremors is rocking the ocean floor off the west coast of Vancouver Island.
Since Tuesday, 17 quakes in the four to five magnitude range centred about 200 kilometres west of Port Hardy have been detected.
Earthquake scientist Garry Rogers with the Geological Survey of Canada said quake swarms happen several times a year in that area, but this one is lasting longer, and the earthquakes are larger, than normal.
"It's just a reminder that we live in a very active area, and that immediately west of Vancouver Island is where new ocean crust is being born, and where we would call a very active geological environment."
The largest so far has been a magnitude 5.2 quake on Aug. 27 at 1:17 p.m. PT, but likely none were felt by anyone on shore, said Rogers.
"The earthquakes are too far off shore to be felt, and they are way too small to cause any tsunami or wave action," he said.
A magnitude 3.4 quake on July 30 west of Seattle in Puget Sound was felt by residents of Vancouver Island.

(CNN) -- A magnitude 6.1 earthquake has rocked Vancouver Island, Canada, Thursday, according to the U.S. Geological Survey.
The temblor's epicenter was located about 95 miles (153 kilometers) west-southwest of Port Hardy, British Columbia, and about 293 miles (472 kilometers) west-northwest of Vancouver, British Columbia.
A 6.1-magnitude earthquake is classified as "strong," the USGS Web site says, capable of causing considerable damage.
The quake was the latest of about two dozen temblors of magnitude 4 or above to strike in the area in the past 48 hours, according to the USGS. A 5.2-magnitude quake was the largest of those, striking the same area Wednesday.
Vancouver Island sits off Canada's west coast. Its main city of Victoria sits at its southern end

There have also been several moderate quakes before the strong one.

Hi master_jim2008. Thanks for posting this. Could you please use the Highlight tool to display the CNN and CBC material? Thank you.

Just moments ago there was another 4.2 quake.
Also judging by the map there was also a 4.2 quake on land.

master_jim2008, I like this story. It's good stuff. forgive me for being so blunt, but management gets a hard on when you don't use the highlight tool. It doesn't matter if ur having problems with it or not because they don't see ur end, only their end. So instead of checking first they scream "use the hightlight tool" I made suggestions when they asked before putting new program in place but I guess nobody got the message. This is a BIG problem on our end because of the fact THEY can't see that we did use the tool, however in these case you didn't. My suggestion in the furture would be USE THE HIGHLIGHT TOOL")lol

There's a very useful discussion in the Forum with tips on highlighting without using the Highlight tool. If anyone does have problems using the tool it's important to let us know so we can track it and try to help out on individual stories. Members can message NowPublic Staffers for assistance.

Are these supposed to be related to that 9.0 in Siberia the other day? I mean they are all plates and have to run into each other so it could happen.
Good luck and stay safe to all you West Coast types!

Laugh if you will, but I have a theory that twice a year, as we switch the angle of the Earth, we see more earthquakes, volcanoes, and hurricanes - not just in one hemisphere - but globally. My thought is that it has something to do with the gravitational pull forces changing ever so slightly - but add up to us seeing/feeling and having more of them.
When I was in college and mentioned this 15 years ago, the geology teacher chuckled and said now wouldn't that be interesting if we could prove it.... but I doubt that's the case.
Scientists have now proven that hurricanes are seasonal, as is a large percentage of volcanoes... so is my theory about earthquakes so off base? It'll be interesting to see what scientists can prove in the coming years - especially since we now know that the Earth's rotation slows just a little bit with each tilt (toward and away from the sun)....

We didn't feel anything in Vancouver here, but it's always a little nerve racking as it could mean that the big one is coming, and that could spell disaster for Vancouver and all the surrounding areas - not to mention the fact that Vancouver is totally unprepared for any kind of earthquake to happen.
