That can be scary, Because of that area has a huge fault that has been locked for a long time and has worried the hell out of people in that area. It that big boy ripped loose a 6.7 will look like an ant compared to an elephant.



A 6.7 magnitude earthquake off the west coast of Vancouver Island at 12:41 p.m. today was felt in Metro Vancouver.


The USGS reported it was at a depth of 25.9 kilometres.


The epicenter was located 135 kilometers south-southeast of the town of Port Hardy on the island, the USGS said in its assessment.


No tsunami warning has been issued.


The website said no there's no "destructive widespread tsunami threat" but earthquakes of this size sometimes generate locate tsunamis that can be destructive along coasts located within a hundred kilometres of the earthquake epicentre. "Authorities in the region of the epicentre should be aware of this possibility and take appropriate action."

Now downgraded to 6.4.

Did not feel a thing sitting on the east coast of the Island. Perhaps that is the difference sitting on highly fractured old magma seafloor (the PNW east of the volcano ring was originally seafloor) rather than a big chunk of more solid ancient plate (aka recent East Coast quake).

Ironically not more than an hour before the earthquake the a district street crew was patching potholes in the lane near me and when they used a vibrating compactor I noticed my chair vibrating up and down to a suprising degree.

As my profile locations suggests (Vancouver Island being part of Juan de Fuca plate), I'm not a big believer in the subduction fault theory being central to plate events in the area (it is labeled 'deformation front' in image). Nor are the earthquakes.

Two strikes against that area- ring of fire & near latitude 50. Something strange happening in both rings.

London is on that ring.

"There were some minor power surges near the epicentre and there was phone network congestion on the northern tip of Vancouver Island, but that was just from everybody picking up the phone to talk about the earthquake."

In the village of Tahsis, the earthquake lasted several seconds, coming in two quick waves, shaking buildings but appearing to cause no damage. There were no injuries in the community of 300, said Sharon Taporowski, who works for the village.

Vancouver Island's two largest communities, Victoria and Nanaimo, did not appear to be affected by the earthquake. There were no reports of damage, said Nanaimo director of development Toby Seward.

In Burnaby, TransLink spokesman Drew Snider said staff in Metrotower II experienced about three minutes of swaying and clanging blinds on the upper floors.

John Cassidy, a seismologist with Natural Resources Canada, said the quake was more likely felt in Vancouver because the buildings were higher.

He noted this type of an earthquake is relatively common, occurring on average every 10 years off the coast of Vancouver Island. The quake, which was at a depth of 23 kilometres, is similar to a 6.6 earthquake in November 2004, which was in the same general area with a similar depth.

The earthquake was on the Nootka fault zone, which runs offshore [from] Vancouver Island and involves the separation of two ocean plates - Juan de Fuca and the Explorer

The epicenter was located 135 kilometers south-southeast of the town of Port Hardy on the island, the USGS said in its assessment. Another earthquake Monday. Same depth, but a little more North West than the previous.

Just came across this for the first time. This is on the same fault and nearby or same location (s) as the recent large earthquakes:

http://en.wikipedia.org/wiki/Maquinna_(volcano)
Maquinna is an active submarine mud volcano on the Coast of British Columbia, Canada, located 16-18 kilometers west of Vancouver Island. It rises approximately 30 m (98 ft) above the mean level of the northeastern Pacific Ocean and lies directly along the southern expression of the left laterial, strike slip Nootka Fault.

Geology

Maquinna is one of the few mud volcanoes documented in the northeast Pacific. It is 1.5 km (1 mi) across, contains a breached caldera and two small summit craters.

Scientific studies of Maquinna showed strong, co-registered thermal, particulate, and unusual oxygen that extends 50 m (164 ft) above the volcano, indicating a water column. This data suggests the volcano is actively venting warm hydrothermal fluids. Vancouver Island and the Coastal Mountains west of the volcano ring is not continent, but raised seafloor.
This active Nootka fault may end as far in as the Meager Creek Volcanic area (that just had the largest recorded landslide in Canada in 2010).
