Experts tracking a tremorous trend in northeastern B.C. notched another data point on April 13. In the early morning hours that day, a fracking-caused earthquake tripped the British Columbia Energy Regulator’s drilling shutdown switch.
The BC Energy Regulator confirmed that 4.2 magnitude quake rattled Wonowon, a small community 88 kilometres northwest of Fort St. John, B.C., in the early hours of April 13.
A fracking operation conducted by U.S. firm ConocoPhillips triggered the tremor, felt by more than 20 Wonowon residents. Fracking involves injecting water or other chemicals underground in order to crack open tight formations containing oil or gas.
The regulator told The Tyee that ConocoPhillips “immediately suspended hydraulic fracturing operations” as per regulations. “Those operations remain suspended and will not resume until further measures are put in place and a plan is submitted to the BCER, focused on mitigating future seismic events.”
The BCER has “advised the company to engage Wonowon residents about these events and the company is actively working on its engagement strategy.”
Many people reported the shaking as “strong” to Earthquakes Canada.
In 2020 seismic hazard expert Gail Atkinson concluded that a 4.5 quake caused by fracking could damage roads and homes located within a five-kilometre radius of the quake’s origin.

What? fracturing the crust isn’t harmless?
The more harmful part of fracking is the injection of water and sand into the crust to introduce pressure. Some of the pressure remains trapped in hard shale, compounding existing tectonic plate pressure.
I couldn’t glance past this title without thinking it had something to do with Johnathan Frakes.
I guess I should also have an on topic comment. Are fraking earthquakes really dangerous? I know earthquakes are scary and the idea that humans can make one should be mind blowing, but I can’t help but think they’ve never been very strong. I guess I would feel differently if I lived in a geologically active area.
