Magnitude 4.8 quake rattles area, but no injuries or damage reported, energy regulator says
CBC News, Jan 12, 2016
A hydraulic fracturing operation near Fox Creek, Alta., has been shut down after an earthquake hit the area Tuesday.
The magnitude 4.8 quake was reported at 11:27 a.m., says Alberta Energy Regulator, which ordered the shutdown of the Repsol Oil and Gas site 35 kilometres north of Fox Creek. Read the rest of this entry
Seismic scientist David Eaton says Canada’s fracking-induced quakes are the biggest in the world
By Betsy Trumpener, CBC News, Aug 27, 2015
A leading seismic scientist says B.C.’s energy infrastructure and gasfield workers may be vulnerable to earthquakes caused by fracking.
Earthquakes triggered by fracking have been felt in Fort Nelson and Fort St. John, but University of Calgary geophysicist David Eaton says the shaking is strongest in remote areas near fracking sites.
B.C. commission draws link between fracking and 231 seismic events in province
By Terry Reith, Briar Stewart, CBC News, April 17, 2015
May Mickelow had just settled into her shift as night auditor at the Foxwood Inn in Fox Creek, Alta., when she felt the rumble.
“You didn’t hear anything, but you could feel the earth move underneath your feet quite strongly, actually,” said Mickelow. “I felt dizzy, as if I was suddenly on uneven footing.”
Some hotel guests descended to the main floor, asking Mickelow if she had felt the shaking. She had been through earthquakes before, but not here. Read the rest of this entry
Quakes also triggered by wastewater disposal, finds oil and gas commission.
British Columbia’s shale gas fracking industry triggered more than 231 earthquakes or ”seismic events” in northeastern British Columbia between Aug. 2013 and Oct. 2014.
Some of the quakes were severe enough to ”experience a few seconds of shaking” on the ground in seven areas of the province on top of the large Montney shale gas basin.
The events, many of which occurred in clusters or swarms, showed that the regulation of the industry still lags behind the pace of drilling activity in the region. Read the rest of this entry
The rivers of water pumped into and out of the ground during the production of natural gas, oil and geothermal energy are causing the Earth to shake more frequently in areas where these industrial activities are soaring, according to a series of studies published today. While the gas extraction process known as hydraulic fracturing (aka “fracking”) causes some small quakes, it’s the disposal of wastewater following that process — and many others relating to energy production — that lead to the largest tremors.
