An Ontario City Was Hit By A Rare Earthquake On Tuesday Morning
This certainly doesn't happen every day!
It's a pretty rare occurrence but one city in the eastern area of the province was hit by a tremor on December 17. Cornwall, near the border with the U.S. state of New York, wasn't damaged by the mini Ontario earthquake. However, there were reports on social media of the ground literally shaking.
According to The Weather Network, the 2.9 magnitude quake was recorded in the area of eastern Ontario on Tuesday, December 17.
Reports started coming in from residents in and around the Cornwall area at about 9:19 a.m. The earthquake struck the southwest area of the city near the St. Lawrence River, which separates Ontario and N.Y.
The epicentre of the seismic event was actually located in Massena, N.Y., which is around a 20-kilometre drive from Cornwall over the river.
Ontario's Ministry of Natural Resources stated that no damages have been reported as a result of the incident.
That's likely because this quake was a very mild one at just under 3 on the Richter scale.
TWN notes that this region of eastern Ontario is actually considerably more susceptible to earthquakes than most places in the province. This is despite the absence of fault lines in the area.
Back in 2013, for example, the St. Lawrence region was hit with a 5.2 magnitude tremor.
That one wasn't far from the largest earthquake that has ever been recorded near that location, which Natural Resources Canada (NRC) states was a 5.8 tremor back in 1732.
Despite the comparative calm of Tuesday's tremor, numerous reports were filed by people who felt the ground shake as a result of the incident.
A graphic from the NRC website shows multiple reports of weak-intensity shaking, mostly around Cornwall and Ingleside.
There were also isolated reports on Twitter, with one person comparing it to the sound and feel of a huge fire truck passing by.
NRC's "earthquake guy", John Cassidy, tweeted some historical context in which he suggests Tuesday's quake may have been the result of a delayed aftershock of an earthquake that hit 75 years ago.
The government site clarifies that there was a 5.8 Cornwall-Massena earthquake in 1944 which caused considerable damage.
An article from the earthquake-tracking site Temblor.com explains that it is believed aftershocks can be felt again even centuries after the initial quake.
Thankfully, Tuesday's tremor was pretty minor.
It was an actual earthquake, though, unlike the shaking ground that residents of Windsor felt last Friday.
Ultimately, that incident wasthat took place across the U.S. border in Detroit, Michigan.
It's been quite the last week for potential quake-spotters.
