What Are These Strange Sounds Heard Over Canada?

This video appears to feature an unexplained phenomenon. “Skyquakes” or “Sky Trumpets” are a series of loud noises that remind many of the sound of a freight train braking suddenly. They are thus far unexplained and when set to the seemingly peaceful backdrop of a quiet neighbourhood scene they are quite eerie and rather ominous. Courtesy: Kimberly Wookey.
