Earthquakes Canada, a part of Natural Resources Canada, has confirmed that a 3.6 magnitude earthquake occurred near Sudbury early Friday morning.

It says the location of the earthquake was 14 kilometres east of Onaping Falls and happened at a depth of 10 km at 2:23 am.

This one was a bit stronger and a little bit closer to Sudbury than the one that happened on Wednesday evening.

Earthquakes Canada tracks data on the extent of shaking and damage reported by the community.  They use this information to help responses to future earthquakes.

Danica Pagnutti is a Corporate & Indigenous Affairs specialist at Vale’s Sudbury operations. 

“A seismic event, with a magnitude of 3.5 on the Nuttli scale, occurred at Creighton Mine this morning at approximately 2:20 am. No employees were underground at the time. Once the affected area is deemed safe, it will be assessed for any damage that may have occurred as a result of the event.” said Pagnutti.

She also confirmed Friday that both seismic events were triggered by mining activity.

Wednesday's 2.9 magnitude earthquake was activated by work at Garson Mine, while Friday's earthquake was caused by work at Creighton Mine.

"Seismicity is frequently associated with mining activity. In this case, the seismicity was of a higher magnitude than we would typically see. Vale takes many measures and precautions to try to minimize the impacts felt by the community as a result of our blasts and to do what we can to prevent seismicity." said Pagnutti.

According to Earthquakes Canada, the last earthquake in the Sudbury area that registered over 3.0, was a 3.8 magnitude quake back in August 2014.

The biggest in the region was a 6.2 magnitude in November 1935 north of Temiscaming.

When asked if residents should anticipate further seismic activity in the coming days, she replied by saying:

"Seismicity is very difficult to predict. Our ground control teams will continue their best efforts to do what they can to minimize the impacts of blasting on the community."

Pagnutti says that safety is the primary focus of Vale's operations and while some residents were alarmed by the events, no one's safety was at risk.
