Some people in Terrace, B.C., say they were awoken Thursday morning by some strange, whining and grinding noises echoing off nearby hills for several minutes.

At least three different people recorded the phenomenon, including Kimberley Wookey, who posted a video on YouTube.

Mandi Campbell described hearing the loud sounds rolling through the hills around the city

"It seemed to be coming from the sky or underground, something so loud though. And I believe it was heard in Hazelton, which is close to here, and as far as the Nass," said Campbell.

Some have speculated the noise is related to last year's earthquake that struck northwestern B.C., or perhaps the 7.0 magnitude quake that struck off the Aleutian Islands on Friday morning.

But Honn Kao of the Geological Survey of Canada said the noise is not related to any seismic activity in the region.

Other popular theories include electromagnetic activity or a train, but residents insist the noises aren't from the nearby train tracks.

Of course they could also be some sort of a hoax or prank. Reports of strange sounds lit up the internet in 2011 as well, when they were dubbed sky trumpets by some.
