The Alberta Energy Regulator is moving to restrict oilfield fracking activity near the Brazeau Reservoir in east central Alberta as a precaution following a 4.3 magnitude earthquake south of the area in March.

The Alberta Energy Regulator received a report from Vesta on March 4 at 6:20 a.m. that seismic activity with a magnitude of 4.32 was detected due to fracturing at the site.

Of the roughly 2,800 earthquakes recorded in Alberta over the past three decades, almost half of those have occurred on prairie land.

Hydraulic fracking is one of the most divisive issues in New Brunswick and it now poses the risk of placing a wedge between all four political parties in the province's legislature. 

Corridor Resources currently has 32 producing wells in the Sussex area and operates a 50 kilometre pipeline, a gathering system comprising 15 kilometres of pipe, and a natural gas processing facility.

Scientists have figured out how hydraulic fracking causes earthquakes in northern Alberta, but they have a way to go before they can use that knowledge to predict if it will cause temblors in other areas.

The Nova Scotia Onshore Petroleum Atlas lists the economic potential of onshore natural gas resources to be between US$20-billion and US$60-billion.

Research suggests hydraulic fracking can cause earthquakes in at least two ways - and one of them can cause tremors months after the activity stops.

New research suggests that hydraulic fracking of oil and gas wells is behind human-caused earthquakes in western Canada.

A record-breaking earthquake this week in the middle of an Alberta oilfield heavily subject to hydraulic fracking is one of a growing number of such events across the continent, scientists say.
