Earthquakes in Iceland — August 2026
2 earthquakes were recorded in Iceland during August 2026, an average of 0.1 per day.
2 reached magnitude 4 or above and 0 reached magnitude 5 or above. The average focal depth was 10 km.
The month's largest event in Iceland was a magnitude 4.4 earthquake near Sandgerði, Iceland on 25 August 2026 at 03:38 UTC. A magnitude 4.4 earthquake radiates roughly 60 tons of TNT equivalent in seismic energy.
That is close to the Iceland monthly average of 2 events over the period we cover, 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.
Activity peaked on 25 August, when 2 events were recorded.
The month's largest events were M4.4 near Sandgerði, Iceland on 25 August at 10 km; M4.2 near Sandgerði, Iceland on 25 August at 10 km.
