Earthquakes in Portugal — February 2026
2 earthquakes were recorded in Portugal during February 2026, an average of 0.1 per day.

The month's largest event in Portugal was a magnitude 5.1 earthquake near Santa Cruz das Flores, Portugal on 09 February 2026 at 22:31 UTC. A magnitude 5.1 earthquake radiates roughly 674 tons of TNT equivalent in seismic energy.
That is well above the Portugal monthly average of 2 events over the period we cover — an unusually active month.
100% of events here are shallow (under 70 km), 0% intermediate (70–300 km) and 0% deep-focus (over 300 km). Almost everything here is crustal. That is characteristic of transform faulting or continental deformation rather than subduction — and it means shaking at the surface is strong for the magnitudes involved.
By band, the catalogue holds 1 in the magnitude 3 range, 1 in the magnitude 5 range.
The month's largest events were M5.1 near Santa Cruz das Flores, Portugal on 09 February at 10 km; M3.5 near Sobral de Monte Agraço, Portugal on 19 February at 10 km.
That is 33% above the 2 events Portugal averages per month across the 10 months on record.
