A very rare earthquake has occurred at a fracking operation located at the Ontario Canada / USA border near Detroit Michigan.
This location in Ontario just so happens to also be a location which had a giant methane burst come out of the ground two years ago (2015).
It would appear that the location in question is vulnerable to seismic pressure as the pressure is coming from the West Coast of the United States + Canada.
This is a screenshot of the fracking / oil / gas pumping operation which was struck.
