Just after 2:30 p.m. on Monday, people in Perth Road Village north of Kingston, Ont., heard a loud bang and felt the ground shake. They thought there'd been an explosion, a crash or even an earthquake.
"Some people said their dogs were startled and started to act weird," said Alex Braun, a geophysicist at Queen's University in Kingston, on Thursday.
"Others went outside and thought there was a car pileup, an accident. Some even mentioned a plane may have crashed in the nearby forest. Others thought there was a blasting event in a nearby quarry."https://www.cbc.ca/news/canada/ottawa/kingston-frost-quake-january-7-2019-1.4972746
