Strange Sounds in the Sky

Filmed in Saint Petersburg, Russia. The description says the sound was accompanied by an earth vibration.

My take: All I can say is O M G! This is the loudest recording I’ve posted. The fact that the earth is vibrating makes it even more intriguing. The famous and very loud Florida video described earth vibrations.  I wasn’t there and it gives me chills. I think if I were there I would run!
