File this under "unexplained phenomena." Or "fantastic internet hoax." You decide.

A video taken in Nova Scotia (reportedly near a place called Apple River, which, yes, sounds like some Granny Smith-colored body of water from a fantasy novel) shows the ground slowly moving up and down, like the way somebody would while sleeping soundly.

Brian Nuttall shot the video and posted it on Facebook, where it inspired all sorts of debate.

Nuttall himself tried to explain it:

The wind was blowing the trees on the hill a few days after the remanence of hurricane Patricia, it was a strong west wind. I walked across a choppins that was logged a few years back. As I entered a patch of trees spared from clear cutting, I noticed the ground moving. I believe the larger trees are doomed to blow down but are currently spared, the smaller trees around them help hold each other up, as the wind pushes the trees into one another. I feel the trees didn't grow deep strong roots as they wouldn't be needed when surrounded by a forest, sheltered with strength in numbers unlike a tree found alone in a pasture. The punishing prevailing winds have taken their toll on the side hill, the roots have loosened and the mossy ground from the once shaded forest floor are giving way, soon to be toppled over. The ground is dry on the side hill, all gravel with shallow top soil(4 to 6 inches) for roots, not wet, no underground rivers.

Whatever it may be, it's part awesome in scope and part terrifying, like there's some mythical creature hiding under the roots waiting to emerge and wreak havoc with all those poor "aww shucks" Canadians who've never done anything bad to anyone (well, aside from nudging Celine Dion south of the border).

What do you think? Does Nuttall make sense? Is this real? Or is it merely a sign the end of times is coming?
