What Caused Alberta’s Record Quake? Check Drilling, Experts Say
A cluster of tremors, including the largest recorded earthquake in Alberta’s history, may have been due to oil and gas activity in the region.

Thousands of Quakes, Tied to Fracking, Keep Shaking the Site C Dam Region
Building the Site C dam in northeastern British Columbia is proving more difficult than officials predicted due to unstable ground on the northern bank. Adding to concerns: myriad earthquakes.
UK Ban Adds to the Tremors Taking Down the Fracking Industry
The dramatic decision by the British government to ban the disruptive technology of hydraulic fracturing (or fracking) is just one of two volatile storms now shaking the industry.
And both have ramifications for the governments of British Columbia and Alberta, which actively subsidize the uneconomic industry with tax breaks, royalty credits, free water and taxpayer-funded seismic research and monitoring.
Spooked by Quakes, Oklahoma Toughens Fracking Rules
After swarms of earthquakes caused by hydraulic fracturing, Oklahoma has introduced tougher regulations than those used by any Canadian energy regulator. Last month the Oklahoma Corporation Commission ordered all drillers to deploy seismic arrays to detect ground motion within five kilometres of hydraulic fracturing operations over a 39,000-square-kilometre area in the centre of the state.
Oklahoma’s Clear Link Between Earthquakes and Energy Boom
Oklahoma geologist Todd Halihan talks about the stunning increase in earthquakes in Oklahoma and what can be done about it.
New Evidence Links Earthquakes to Fracking
The evidence linking fracking to earthquakes continues to pile up.
Swarms of Earthquakes Shake Up Shale Gas Fields
The locals call it "incoming," and some compare the violence of the tremors to living in a war zone. Others say it’s like having their homes hit by a truck. The scene is north Texas…
