Small earthquake off Vancouver Island followed by over a dozen aftershocks



Few likely felt it, but a small earthquake off the coast of Vancouver Island this morning has caused more than a dozen aftershocks.

A 5.1-magnitude earthquake registered around 180-kilometers west of Port Hardy at 7:49 this morning.

Seismologist Taimi Mulder with Geological Survey of Canada says the dozen or so aftershocks that have registered since is not unusual.

"They are occurring on the boundary between the Pacific plate and the northern end of the Juan de Fuca plate system. So we get about a magnitude five once, maybe twice a year on these offshore ridge area, and we often see a lot of aftershock activity."

Mulder says the aftershocks could continue for a few days but the magnitude and frequency of the tremors are already dropping.
