Saskatchewan was hit with a rare earthquake Monday morning.
The quake happened around 4:40 A.M.
Hon Kao, a Research Scientist for Natural Resources Canada, says the quake wasn’t very strong. but it was enough for people to notice it.
EarthQuakes Canada says it was centred about 32 kilometres east-southeast of Yorkton.
SaskPower reported a outages in the area affecting Moosomin, Rocanville, Whitewood, Esterhazy, Stockholm and Wapella.
A switching station was affected and it took out power to about 2,000 residential customers.
The Potash Corp mine near Rocanville had to switch to backup power.
But nearly 40 people were stuck underground as there wasn’t enough power to operate the hoists which lift the workers to ground level.
According to a Potash Corp spokesperson, the workers were slowly brought back up to the surface – the last lifted out at about 11:30 Monday morning.
Those caught underground went to refuge stations with power, air, and water until the power came back on.
According to Natural Resources Canada, there have been 12 earthquakes in the region at magnitude 3.0 or higher since 1981.
However, Monday’s quake was the largest reported according to Kao.
In 2012 there was an earthquake reported near Esterhazy.
