4.2 magnitude earthquake near Fort St. John

An earthquake struck a region in the northeast of B.S. near Fort St. John on Thursday after 5pm. PT.

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

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

Honn Kao, a researcher at the Geological Survey of Canada, said that early evidence suggests that the earthquake has a relatively small depth, which is probably due to why the earthquake is widely felt.

“This is definitely an event that is felt by the locals,” said Kao. “Although this is a significant event for the region, I don’t think it causes significant damage.”

Hydraulic break in the area

Although it is unconfirmed, what caused this earthquake, Kao said that B.S. The Oil and Gas Commission is investigating whether the earthquake is related to hydraulic fracturing operations in the area.

Hydraulic fracturing — or wear — is when water, sand, and other chemicals are introduced underground under very high pressure to destroy shale rock deep underground to produce natural gas.

“They will need to link the location and time of this event to the injection operations nearby,” said Kao.

This area of ​​the country is western Alberta and northeast B.C. – According to a study conducted at the University of Alberta, there is a high rate of earthquakes caused by cracks.
