What did shake houses and create a loud boom in Toronto, Newmarket, Aurora, Belleville, Richmond Hill, and Sutton. A meteor explosion?, An earthquake? An army plane (sonic boom) or even Santa farting? Nobody knows, but almost everybody heard it!
People in the grand area of Toronto were surprised by a huge detonation at around 11 p.m. on Christmas Eve. As reported by Global News, “Not only was the boom heard, but it rattled houses, leaving many to believe that a tree had fallen on their rooftop.”
According to the same source, similar strange and loud booms were heard at other times of the day as well 8 (from 2 p.m. to 6 p.m. to 1 a.m. on Christmas morning).
So what was it?
Plenty of meteor explosions over the same area would be more than curious. The United States Geological Service (USGS) didn’t record any seismic event in Ontario yesterday, and there were no reports to the American Meteor Society. I believe army pilots are also having dinner with their families on Christmas Eve. And, finally, if he exists, Santa would have had to eat too many beans to produce such explosion-like noises.
Another explanation for these booms, and probably the most likely, is cryoseism or frost quake.
As explained by Nicole Mortillaro from Global News, “cryoseisms are rare, localized seismic events that occur when a sudden drop in temperature freezes the groundwater, which then expands and cracks the soil and rock. The crack will release a sudden burst of explosive energy, resulting in a loud noise and the shaking of the ground. They usually occur between midnight and dawn. Temperatures north of the city — in Newmarket, Richmond Hill, and Sutton, for example — were a chilly -20 C or colder on Christmas Eve.
In 2000, 12 frost quakes were recorded in two hours in Sadowa, Ontario. Moreover, two similar events took place in southwestern Ohio and Indiana in 2011 and in Ohio in 2007. Here is what people think about the frostquake explanation! What do you think is the source of this still unexplained loud boom?
