A 3.5 magnitude earthquake was recorded at 10:42 am Thursday near Beaupré. The earthquake was slightly felt in the Quebec City area.
It occurred at the same height as another felt on January 2, between Saint-Vallier and Berthie-sur-Mer, south of the St. Lawrence River.
The weak shock did not cause any damage, but it may have been felt as far as Saint-Augustin-de-Desmaures.
The earth had trembled in the same area Tuesday night , in the St. Lawrence River, facing the Côte-de-Beaupré. The tremor, of magnitude 3 at that time, had no consequences either.
Geological Survey of Canada seismologist Maurice Lamontagne explains that the two close earthquakes are from the same source, the former being the precursor of the second.
“Sometimes, it happens to have events like this that happen quickly in time, and we call it a swarm of earthquakes if it continues with more events. But so far, there are just two earthquakes that have occurred, “he says.
Despite two shocks in a short time, the situation is not alarming, says Lamontagne.
“There is no reason to be alarmed. We will follow the situation with our network of seismographs, but if people think about the earthquake, it might be time to see if they have all that would be needed if there ever was one more strong that can occur this year as in 10 or 15 years. ”
He explains that the epicenter was at a depth of 10 to 20 kilometers below the surface of the St. Lawrence River.
