An earthquake hit an area in the northeast B.C. near Fort St. John on Thursdays after 5 p.m. PT.

According to the US Geological Survey, the earthquake had a preliminary magnitude of 4.2 and the epicenter was 22.4 kilometers southeast of Fort St. John.

People at Fort St. John, as well as Taylor, Chetwynd and Dawson Creek reported hearing the earthquake on social networks, but there are currently no reports of damages.

Honn Kao, a scientific researcher at the Geological Survey of Canada, said early data suggests that the earthquake had relatively little depth and that it is likely that the earthquake would be widely felt.

"This is certainly an event that local residents felt a bit," Kao said. "Although this is a significant event for the region, I do not think that it causes significant damage."

Hydraulic fracture in the zone

Although it was not confirmed what caused this earthquake, Kao said the B.C. The Petroleum and Gas Commission is investigating whether the earthquake is related to hydraulic fracturing operations in the area.

The hydraulic fracture – or fracking – is when water, sand and other underground chemicals are injected at a very high pressure to break the slate stone into the bottom of the ground to extract natural gas.

"They should link the location and time of this event to the next injection operations," Kao said.

This area of ​​the country – western Alberta and northeast B.C. – It has a high rate of earthquakes induced by fracking, according to a study by the University of Alberta.
