Three earthquakes were detected off the coast of Vancouver Island on Friday morning

A trio earthquakes struck the western coast of Vancouver Island within a one hour period at the same location this morning.

All three hit between 170 and 181 kilometres west of Port Hardy  depth of 10 kilometres

The first of three seismic events occurred at 7:49 am was also the strongest, a magnitude 5.1 tremor.

The second tremor struck less than an hour later at 8:42 a.m with a magnitude of 4.3.

And then a third and final tremor hit just 10 minutes later at 8:52 am with a magnitude 4.6

It’s possible the second two quakes were aftershocks from the initial magnitude 5.1 tremor.

All the earthquakes had a depth of 10kms and Earthquakes Canada said there were no reports of damage and none would be expected.

British Columbia sees thousands of tremors every year, but only a few reach a magnitude of more than four.
