FORT ST. JOHN, B.C. — The BC Oil and Gas Commission says that a magnitude 3.6 earthquake that struck northwest of Fort St. John earlier this week was not related to fracking.

According to seismograph data, the M3.6 earthquake struck at a depth of five kilometres just north of Wonowon shortly after 7:30 p.m. Wednesday. BC OGC spokesperson Phil Rygg said that the Commission has investigated, and found that there was nothing to indicate that any industry activity occurred within 15 kilometres of the earthquake’s epicentre.

This earthquake is one of three that have occurred in the North Peace region in the last 30 days. The first was a M2.4 earthquake which occurred southwest of Wonowon on January 18th, also at a depth of 5 kilometres. Another M3.5 earthquake happened northeast of Sikanni Chief last Sunday evening shortly before 11:00.

Seismologist Taimi Mulder with the Geological Survey of Canada said that any earthquakes induced by oil and gas activities tend to occur less than five kilometres below the Earth’s surface.
