At least two earthquakes in British Columbia over the past year – including one last week – are among the largest ever caused by natural gas fracking in North America and were both strong enough to force temporary shutdowns of operations.

But while the province’s oil and natural gas ministry as well as the shale gas industry have both played down the severity of fracking-induced quakes – insisting they are rare and present no threat to people or buildings – experts caution much is still not known about just how strong a fracking-induced earthquake could be.
