Natural Resources Canada said a 4.6-magnitude earthquake rocked parts of central Alberta just before 6 a.m. The federal department’s website said the tremor was classified as a light earthquake.
The AER has confirmed Vesta Energy had been fracking in the area just prior to the quake, which was detected by the company’s private seismic monitoring devices around 12 kilometres south of Sylvan Lake at a magnitude of 4.16. #abpoli #ableg
