Earthquakes in Iran — May 2025

7 earthquakes were recorded in Iran during May 2025, an average of 0.2 per day.

7 reached magnitude 4 or above and 2 reached magnitude 5 or above. The average focal depth was 10 km.

The month's largest event in Iran was a magnitude 5.2 earthquake near Kūh Sefīd, Iran on 28 May 2025 at 21:30 UTC. A magnitude 5.2 earthquake radiates roughly 951 tons of TNT equivalent in seismic energy.

That is close to the Iran monthly average of 8 events over the period we cover, and up 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 5 in the magnitude 4 range, 2 in the magnitude 5 range.

Activity peaked on 08 May, when 2 events were recorded.

The month's largest events were M5.2 near Kūh Sefīd, Iran on 28 May at 10 km; M5.0 near Dehdasht, Iran on 27 May at 10 km; M4.8 near Torbat-e Ḩeydarīyeh, Iran on 01 May at 10 km.

That is close to the 8 events Iran averages per month across the 21 months on record.
