Magnitude 3.7 earthquake strikes Ontario and people were very confused

Ontario residents may have noticed some unexpected rattling on Tuesday night, the result of a magnitude 3.7 earthquake felt across much of the province's central and southern regions.

Natural Resources Canada states that the tremor occurred at 10:59 p.m. on Tuesday night, just northeast of Barrie, Ont., at a depth of five kilometres below ground.

While this was nowhere near the destructive power of the higher-magnitude earthquakes that occur in major fault zones, any tremor that causes noticeable shaking in less earthquake-prone regions, like Toronto, is a rare experience for locals.

Yup! Heard a low grumbling sound and then our bed shook

Despite the relatively low magnitude, the shaking was apparently significant enough to cause minor damage in one home. One person reported that their closet collapsed following the minor quake. However, Natural Resources Canada downplays reports of damage, stating that "There are no reports of damage, and none would be expected."

Only thing weirder than my closet literally falling apart in the middle of the night was having an #earthquake in Ontario pic.twitter.com/oys3NPEjbf

Following the huge storm that struck the province on Sunday, at least a few people understandably thought the rattling ground was due to passing snowplows.

I thought it was a snow plow...

Granted, with the quake occurring on a weeknight at roughly 11 p.m., many locals just peacefully slept through the shaking and only learned about it upon waking up in the morning.

Gorgeous water scene…happy mid week my friend..

According to Natural Resources Canada, much of central and southern Ontario is assessed as a "low" seismic hazard area, including the area where Tuesday's minor rattling occurred.

However, other areas of the province, most notably areas near Ottawa and North Bay, have a much higher risk of earthquakes, and seismic events are generally stronger than those felt in the province's southernmost areas.
