A magnitude 4.6 earthquake struck 92 km WSW of Ferndale, California on 05 Nov 2026, 04:56 UTC. The hypocentre was 8 km below the surface — shallow by seismological convention. This is an automatic solution that an analyst has not yet reviewed, so the magnitude and depth above may still change. 2 other earthquakes above our reporting threshold have been recorded within 250 km in the past 30 days.

MAGNITUDE 4.6

Noticeable shaking of indoor objects. Damage is unlikely.

The scale is logarithmic: this released about 250 times the energy of a magnitude 3.0, roughly the energy of 120 tonnes of TNT.

8 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.
