The B.C. The Oil and Gas Commission blamed fracking for three earthquakes in the northeast of the country. last month.

The provincial regulator said events 20 kilometers south of Fort St. John on Nov. 29 occurred due to fluid injections during the hydraulic fracturing at a site at the Canada Natural Resources well.

The events, which were felt but did not cause surface damage, measured 3.4, 4.0 and 4.5 magnitude.

Fracking operations within the lower Montney formation, a major shale oil and gas resource near the BC-Alberta border, were suspended after earthquakes and should remain suspended in the multi-well block pending the results of a technical review detailed.

The commission says seven wells in Montney's upper education were previously drilled and completed by the Calgary-based company with no seismic events higher than the 2.5 magnitude detected.

Immediate shutdown of operations is required when a seismic event induced in that region reaches or exceeds a magnitude of 3.0.

Hydraulic fracturing involves the injection of water, sand and chemicals into a well under pressure to break the tight underground rock and free of oil and gas trapped.
