This followed a 5.5 magnitude quake recorded at 4:30 a.m. and another 4.2 magnitude quake recorded about an hour and a half earlier near the same location.

The agency said it is currently monitoring a swarm of earthquakes far off the coast of northern Vancouver Island. There have been more than 30 temblors since Sept. 14, though none have been felt, with the largest being Sunday's 5.5-magnitude quake.

Andrew Schaeffer, a seismologist with Natural Resources Canada, said seismic activity in that area is "completely common."

He explained the quakes took place in a region called the Queen Charlotte Triple Junction, where three tectonic plates meet.

"As a result, we get quite a bit of seismicity in this area," Schaeffer said in an interview Sunday. "Sometimes it comes in swarms, sometimes it's just kind of continuous normal background seismicity."

Schaeffer said it is not possible to predict whether more will occur.

"It's not a function of weather or time of year, just sometimes the swarm will happen. Otherwise it's pretty normal for a magnitude 3.0 to pop off every month, at least, in that area and then sometimes we just get these bursts of activity."

There are no reports of any damage from Sunday's quakes and no tsunami is expected, Schaeffer said.

"For us on the west coast, (earthquakes) are just another reminder that we live in an active earthquake zone and let's be prepared."

He suggested people ensure they have an 'earthquake preparedness kit' on hand and formalize a family emergency plan so they are ready in the event of a natural disaster.
