Officials with Environment Canada are reporting an earthquake shook the ground in northwestern Alberta late Tuesday morning.

According to Environment Canada, the 4.5 magnitude earthquake happened just before 11:30 a.m. Tuesday, between Jasper and Fox Creek, Alberta.

Officials said the quake was lightly felt in Fox Creek – and there were no reports of damage.

The Alberta Energy Regulator (AER) said the seismic event took place about 34 kilometres west of Fox Creek – and it had a magnitude of 4.8.

AER officials said an investigation into the cause was underway, and they couldn’t confirm whether it was caused by hydraulic fracking.

AER said when seismic activity higher than 4.0 magnitude happens, companies affected by it have to stop their operations, and contact AER.

According to AER, one company had to stop operations, and will continue to, until AER approves plans to resume work.

It’s not clear how far the earthquake reached, officials said.
