Earthquakes in Portugal — March 2025
3 earthquakes were recorded in Portugal during March 2025, an average of 0.1 per day.
3 reached magnitude 4 or above and 1 reached magnitude 5 or above. The average focal depth was 10 km.
The month's largest event in Portugal was a magnitude 5.3 earthquake near Povoação, Portugal on 11 March 2025 at 08:14 UTC. A magnitude 5.3 earthquake radiates roughly 1,344 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, and up from the 1 recorded the previous 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 2 in the magnitude 4 range, 1 in the magnitude 5 range.
The month's largest events were M5.3 near Povoação, Portugal on 11 March at 10 km; M4.4 near Faro, Portugal on 24 March at 10 km; M4.3 near Mosteiros, Portugal on 25 March at 10 km.
That is 100% above the 2 events Portugal averages per month across the 10 months on record.
This month also holds the strongest earthquake recorded in Portugal in our entire catalogue.
