Sudbury experienced multiple seismic events in October 2025, including a magnitude 3.5 earthquake on October 24 at 11:20 a.m., located 15 km southwest of the city. This event was confirmed to be mining-related, originating from Vale's Creighton Mine, and was detected by Earthquake Canada and the US Geological Survey. The quake was shallow, at about 10 km depth, and felt by residents across Greater Sudbury, with reports of house shaking, loud rumbling, and feeling it in various neighborhoods. Earlier, on October 19, a magnitude 3.5 seismic event occurred at Creighton Mine, and on October 22, a magnitude 3.0 earthquake was recorded approximately 3 km north-northwest of Lively, also linked to mining activities. These earthquakes, though minor, caused noticeable ground shaking but no damage. The USGS and Earthquake Canada confirmed the seismic activity was related to mining operations, specifically blasting and rockbursts at Creighton Mine, which are common in the area. Residents and officials are monitoring the situation, and more data is expected to clarify the magnitude and impact of these seismic events.
