For weeks, residents of Windsor, Ont., have been complaining about a mysterious rumbling that is shaking them out of sleep. So far no one - including the Ontario Ministry of the Environment and the federal agency Earthquakes Canada - has any idea why. Al Maghnieh is a city councillor for a vibrating Ward 10. CBC Radio's As It Happens reached him on Friday.

I looked up the Geology of the Great Lakes and found their estimated formation interesting:
"It has been estimated that the foundational geology which created the conditions shaping the present day upper Great Lakes was laid from 1.1 to 1.2 billion years ago, when two previously fused tectonic plates split apart and created the Midcontinent Rift, which crossed the Great Lakes Tectonic Zone. A valley was formed providing a basin that eventually became modern day Lake Superior. When a second fault line, the Saint Lawrence rift, formed approximately 570 million years ago, the basis for Lakes Ontario and Erie were created, along with what would become the St. Lawrence River."
Perhaps a tectonic shift is about to happen again. Perhaps a hot spot.
Then again, Windsor is right on the border of the US so it could be Detroit is doing something underground. Perhaps constructing a tunnel or underground shelters. Maybe an underground tunnel to smuggle illegal trade through borders. No telling what lies beneath our feet.
I can not wait to find out what it is. What ever became of the hum in Northern England?
