Earthquakes in Iceland — April 2025
4 earthquakes were recorded in Iceland during April 2025, an average of 0.1 per day.
4 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 Iceland was a magnitude 5.2 earthquake near Vogar, Iceland on 01 April 2025 at 16:54 UTC. A magnitude 5.2 earthquake radiates roughly 951 tons of TNT equivalent in seismic energy.
That is well above the Iceland 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 3 in the magnitude 4 range, 1 in the magnitude 5 range.
Activity peaked on 01 April, when 3 events were recorded.
The month's largest events were M5.2 near Vogar, Iceland on 01 April at 10 km; M4.9 near Grindavík, Iceland on 01 April at 10 km; M4.6 near Vogar, Iceland on 01 April at 10 km.
That is 70% above the 2 events Iceland averages per month across the 14 months on record.
