Earthquakes in Iran — December 2025
4 earthquakes were recorded in Iran during December 2025, an average of 0.1 per day.
4 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 Iran was a magnitude 4.6 earthquake near Qūchān, Iran on 06 December 2025 at 16:46 UTC. A magnitude 4.6 earthquake radiates roughly 120 tons of TNT equivalent in seismic energy.
That is below the Iran monthly average of 7 events over the period we cover — a comparatively quiet month, and down from the 5 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 4 in the magnitude 4 range.
The month's largest events were M4.6 near Qūchān, Iran on 06 December at 10 km; M4.5 near Sarpol-e Z̄ahāb, Iran on 09 December at 10 km; M4.3 near Gerāsh, Iran on 19 December at 10 km.
That is 45% below the 7 events Iran averages per month across the 22 months on record.
