UPDATE: BC Oil and Gas Commission spokesperson Phil Rygg said that the Commission has investigated the earthquake and found that there is nothing to indicate that any industry activity occurred within 15 kilometres of the earthquake’s epicentre.

FORT ST. JOHN, B.C. — Scientists with the Geological Survey of Canada have confirmed that an earthquake occurred in the Wonowon area on Wednesday evening.

According to seismograph data the earthquake, which measured 3.6 on the moment magnitude scale, struck at a depth of five kilometres just north of Wonowon shortly after 7:30 p.m. 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 earthquake happened northeast of Sikanni Chief last Sunday evening shortly before 11:00, this time with a magnitude of 3.5.

Seismologist Taimi Mulder said that the vast majority of naturally-occurring earthquakes in Northeast B.C. tend to occur within the first 10 kilometres of the surface, as the Earth’s crust is only roughly 20 kilometres deep in this part of the continent. Mulder said that officials with the BC Oil and Gas Commission are responsible for determining whether the earthquake was induced by oil and gas-related activity in the area.

BC Oil and Gas Commission spokesperson Phil Rygg said that the Commission has the earthquake and found that there is nothing to indicate that any industry activity occurred within 15 kilometres of the earthquake’s epicentre.
