A minor earthquake struck British Columbia’s Sunshine Coast on Friday, shaking homes and prompting emergency alerts across the Lower Mainland but causing no significant damage. The 4.7-magnitude tremor, which hit near the coastal town of Sechelt just before 1:30 p.m. PT, was widely felt from Vancouver Island to Metro Vancouver and as far east as the Okanagan and into parts of Washington state.
Immediate Impact and Public Reaction
Although no injuries or major structural damage were reported, some residents described the experience as unsettling. “I heard a loud boom, and then the house shook,” said Jackie Graham, a resident of Courtenay on Vancouver Island. “At first, I thought a tree had fallen on the house.”
Many people reacted by following earthquake preparedness protocols. Workers and students ducked under desks, while others grabbed essential items and evacuated buildings. At an IGA grocery store in Sechelt, customers and staff quickly exited the building. “It was a similar feeling to when a vehicle crashed into the mall, but this one increased gradually and lasted about 10 to 20 seconds,” said store manager Derek Bland. Employees gathered at a designated muster station in the parking lot until authorities confirmed it was safe to return.
Transportation and Infrastructure Inspections
The earthquake triggered precautionary inspections at key infrastructure sites. B.C. Ferries temporarily evacuated and assessed its Horseshoe Bay terminal in West Vancouver, a major transportation hub connecting the mainland with Vancouver Island and the Sunshine Coast. Following a brief disruption, ferry operations resumed with a warning of potential delays. “Safety is always our top priority, and we appreciate everyone’s patience during this process,” B.C. Ferries stated.
Earthquake Early Warning System and Aftershock
The event activated Canada’s Earthquake Early Warning (EEW) system, which provides critical seconds of advance notice to residents in affected areas. The system sends automatic alerts through local cell towers, radios, and TVs. While the alert functioned as expected, Natural Resources Canada announced an investigation into reports from individuals who did not receive notifications despite being within the shaking zone.

A minor aftershock, measuring magnitude 1.9, followed at approximately 2:40 p.m. PT. Seismologists note that aftershocks are common after an initial earthquake and are generally weaker in intensity.
Scientific Context and Preparedness
Sheri Molnar, an associate professor at Western University specializing in seismic activity in Metro Vancouver, emphasized that earthquakes of this magnitude occur in the region roughly once per decade. She referenced previous events, such as the 4.7-magnitude quake near Sidney in 2015 and the stronger 6.8-magnitude Nisqually earthquake in 2001.
“We should always be prepared for an earthquake,” Molnar stated. “While this was a minor event, stronger quakes are possible, and readiness is essential.”
Experts continue to warn that B.C. is in an active seismic zone where a much larger earthquake, sometimes referred to as “the big one,” is anticipated in the future. Emergency Info B.C., the province’s crisis response agency, reiterated the importance of preparedness, encouraging residents to assemble emergency kits and establish family evacuation plans.
No Tsunami Threat Confirmed
Despite initial concerns, authorities quickly confirmed that the earthquake posed no tsunami risk. Tsunami threats typically arise from underwater seismic events, particularly those involving significant fault movement. Officials reassured the public that this particular quake’s depth and characteristics did not indicate a tsunami hazard.
Final Thoughts
While Friday’s earthquake rattled nerves across southwest B.C., it ultimately served as a wake-up call for residents and officials alike. The event reinforced the importance of earthquake preparedness and the effectiveness of early warning systems. As seismic activity continues to be a reality for the region, experts urge communities to remain vigilant and proactive in their emergency planning.
