A series of three large earthquakes have struck off the coast of British Columbia, according to the United States Geological Survey.

Three in a row 'unusual'
CBC meteorologist and seismologist Johanna Wagstaffe said the earthquakes are a reminder that B.C. is in a "complicated" tectonic setting.
"If any one of these quakes had hit closer to land, there would have been devastating consequences," said Wagstaffe.
"Three large ones in a row does seem unusual and I'm sure scientists will be learning as much as they can over the next couple of days about the change in stresses just off our coast."
Looking forward to more info tmrw but preliminary assessment this <a href="https://twitter.com/hashtag/earthquake?src=hash&ref_src=twsrc%5Etfw">#earthquake</a> not in our subduction zone (too shallow for one) & of strike-slip orientation (horizontal movement which is why no tsunami threat). We live in a complicated tectonic setting!—@JWagstaffe
There were no immediate tsunami warnings following the earthquakes.
Earthquakes Canada also reported a magnitude-4.4 aftershock from the first quake before midnight.
