Residents in the vicinity of Sturgeon County, north of Edmonton, have been enduring a series of earthquakes over the past three weeks, causing noticeable disturbances in their homes and daily lives. With a significant increase in seismic activity attributed to industrial operations, local residents are raising concerns about the implications for their safety and the environment.
A New Reality for Sturgeon County
Kalle MacDonald, a long-time resident of Sturgeon County, described his unsettling experience with earthquakes. “I’ve lived here for 30 years, and on April 1, I felt something I had never expected—an earthquake,” he recounted. While he noted that the tremors haven’t caused structural damage, the loud noises and disruptions have been a source of annoyance. “They can strike at any hour, day or night,” he explained. “It’s not so much the damage they do; it’s just the nuisance of it.”
His sentiments resonate with many in the area, as reports indicate that over 30 earthquakes have been recorded in the region recently. The Alberta Energy Regulator (AER) categorises these seismic events as “known induced,” indicating that they are not of natural origin.
Alarming Statistics on Seismic Activity
Data from the AER reveals a troubling trend. Between January and March 2025, the province experienced 862 seismic events, which surged to 1,520 during the same period in 2026. Earthquakes Canada has identified at least seven incidents with magnitudes of 2.5 or above, all linked to industrial activities, including three that exceeded a magnitude of 4.
Stephen Crane, a seismologist from Natural Resources Canada, noted, “Historically, this area has seen very few earthquakes. The majority of recorded seismic activity has occurred in the last three weeks.” He explained that the intensity of felt tremors depends on both the earthquake’s magnitude and the distance from its epicentre. “Generally, damage begins to occur with earthquakes of magnitude five or greater,” he added.
Industry Responses and Regulatory Oversight
Alberta’s Ministry of Environment and Protected Areas has confirmed that the seismic events are associated with operations conducted by Shell Canada, particularly at the Scotford Upgrader and related CO2 injection sites. A ministry statement indicated that Shell is responsible for ensuring the safety of its injection wells before resuming operations, which may involve adjusting injection thresholds or implementing new mitigation strategies.
Energy and Minerals Minister Brian Jean acknowledged the seriousness of industry-related quakes, emphasising the need for vigilant oversight. “When these events occur, we receive reports, and necessary adjustments are made based on the technology used or the operator’s practices,” he stated. “We are conscientious about supervising these situations closely.”
The AER has indicated that while there may be further seismic activity in Sturgeon County, a decrease in tremors is anticipated in the days to come.
Community Concerns and Future Outlook
For residents like MacDonald, the sudden onset of these tremors is baffling. “It’s bizarre to go from experiencing virtually no earthquakes to over 30 in less than a month,” he remarked. MacDonald expressed a desire for accountability from those responsible for the induced seismicity, suggesting that if these events can be induced, they can also be mitigated.
Why it Matters
The rise in induced seismic activity in Sturgeon County raises significant concerns about the intersection of industrial operations and community safety. As Alberta continues to balance economic development with environmental integrity, the experiences of residents highlight the urgent need for comprehensive monitoring and regulation of industrial practices. Ensuring that local communities are protected from the impacts of such activities is paramount, as the consequences may extend beyond mere inconvenience, potentially affecting the very fabric of community life and environmental health.
