The U.S. Geological Survey is reporting a 3.6-magnitude earthquake centered in southern Canada that also was felt in suburban Detroit.
The quake was recorded late Thursday near Amherstburg, Ontario, a town of about 21,900 people.
Jeff Ward of Taylor, Michigan, told the Detroit Free Press he was on his couch watching television when the ground started shaking.
He says a rumbling sound made him think a truck was passing on nearby Interstate 94.
But his understanding changed when the sound continued and the house started shaking.
