On March 29, 2026 at 17:50 UTC, a magnitude 4.2 shallow crustal earthquake struck 212 km W of Port McNeill, Canada, at a depth of 10.0 km and coordinates 50.6939°, -130.0873°. The nearest populated place is Port Hardy (population 4,132).

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 4.2 earthquake near Port McNeill, Canada?

The magnitude 4.2 earthquake that struck 212 km W of Port McNeill, Canada on March 29, 2026 at 17:50 UTC had a depth of 10.0 km. 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 4.2 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.
