Earthquakes in Iran — May 2026

11 earthquakes were recorded in Iran during May 2026, an average of 0.4 per day.

11 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 4.9 earthquake near Sarpol-e Z̄ahāb, Iran on 05 May 2026 at 20:53 UTC. A magnitude 4.9 earthquake radiates roughly 338 tons of TNT equivalent in seismic energy.

That is well above the Iran monthly average of 8 events over the period we cover — an unusually active month, 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 11 in the magnitude 4 range.

Activity peaked on 19 May, when 2 events were recorded.

The month's largest events were M4.9 near Sarpol-e Z̄ahāb, Iran on 05 May at 10 km; M4.9 near Bandar Abbas, Iran on 21 May at 10 km; M4.8 near Noşratābād, Iran on 04 May at 10 km.

That is 46% above the 8 events Iran averages per month across the 21 months on record.
