USGSAUTOMATICTSUNAMI THREAT

A magnitude 5.0 earthquake struck 163 km W of Port McNeill, Canada on 28 Sept 2026, 09:13 UTC. The hypocentre was 12 km below the surface — shallow by seismological convention. No felt reports have been received so far. The reporting agency flagged a tsunami threat for this event; follow official warnings rather than this page. This is an automatic solution that an analyst has not yet reviewed, so the magnitude and depth above may still change. 4 other earthquakes above our reporting threshold have been recorded within 250 km in the past 30 days.

Depth: 12 km

MAGNITUDE 5.0

Can damage poorly constructed buildings; well-built structures usually escape with little harm.

The scale is logarithmic: this released about 32 times the energy of a magnitude 4.0, roughly the energy of 477 tonnes of TNT.

12 KM DEEP

Shallow earthquakes release their energy close to the surface, so they are felt more strongly, and do more damage, than deeper earthquakes of the same magnitude.
