On February 1, 2026 at 17:41 UTC, a magnitude 4.0 shallow crustal earthquake struck 40 km NW of Swan Hills, Canada, at a depth of 10.5 km and coordinates 54.9910°, -115.8082°. The earthquake was reported felt by 5 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.7 (moderate). The nearest populated place is Swan Hills (population 1,900).

Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 4.0 earthquake near Swan Hills, Canada?

The magnitude 4.0 earthquake that struck 40 km NW of Swan Hills, Canada on February 1, 2026 at 17:41 UTC had a depth of 10.5 km. It was felt by 5 people with maximum shaking intensity of MMI 4.7 (moderate). For context, this was a light earthquake commonly felt near the epicenter.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.0 earthquakes can continue for several days and gradually diminish over time.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
