Unexpected Shakes in Saguenay: What Actually Happened?
Residents of the Saguenay region were surprised this past weekend and early this week by a series of seismic events. While Quebec isn’t typically known for frequent earthquakes, several people felt the ground move, sparking curiosity and concern across social media.
Two distinct seismic events were recorded by Natural Resources Canada, hitting the region on Saturday night and again on Monday morning at 8:23 AM. These tremors, measured at 2.7 and 2.8 on the Richter scale, were concentrated around the Saint-Honoré area.
The Connection to the Niobec Mine
The epicenter of both events was located directly beneath the Niobec mine in Saint-Honoré. According to official reports, these tremors are directly linked to the niobium extraction activities at the site.
In a statement shared via Facebook, the company clarified that underground mining operations often cause the surrounding rock mass to readjust. This phenomenon, known as mining-induced seismicity, is a recognized aspect of deep-earth extraction.
Safety Measures and Local Impact
Safety remains the top priority for the mining operation. Following the Monday morning tremor, the Niobec mine took the following precautions:
- n
- Immediate Interruption: The day shift for underground departments was halted.
- Evacuation: All workers were safely brought to the surface.
- Monitoring: Constant surveillance of the rock mass is ongoing to prevent further risks.
How Far Were the Tremors Felt?
While the epicenter was in Saint-Honoré, the impact extended beyond the immediate vicinity. Natural Resources Canada indicated that the seismic waves radiated between 20 to 40 kilometres. This explains why many residents in Jonquière reported feeling the vibrations, leading to a surge of reports on local community forums.
Although these events were unsettling for some, the low magnitude suggests that they pose a minimal risk to surface structures, though they serve as a reminder of the dynamic nature of the Saguenay geological landscape.
