Earthquakes in Iran

Seismic activity in Iran is moderate by global standards, with 5 events recorded in the past 30 days, and 14 of the events on record reached magnitude 5 or above — the level at which damage becomes a genuine concern for vulnerable construction. Activity here is almost entirely crustal, which means shaking at the surface is strong relative to the magnitudes involved.

161 earthquakes have been recorded in Iran in our catalogue, 5 of them in the past 30 days.

The average magnitude is 4.5 and the average focal depth 13 km. 160 events reached magnitude 4 or above and 14 reached magnitude 5 or above.

The strongest earthquake recorded in Iran in this period was a magnitude 5.4 event near Bam, Iran on 05 August 2025, at a depth of 57 km. A magnitude 5.4 earthquake radiates roughly 1,898 tons of TNT equivalent in seismic energy.

Locations recording the most events include Mohr (31), Ḩājjīābād (7), Gerāsh (7), Bandar Abbas (7), Mīnāb (6).

99% of events here are shallow (under 70 km), 1% 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.

The deepest event on record here was a magnitude 4.3 earthquake at 81 km beneath Kūh Sefīd, Iran on 26 July 2026.

By band, the catalogue holds 1 in the magnitude 3 range, 146 in the magnitude 4 range, 14 in the magnitude 5 range.

The busiest single day was 13 February 2026, with 6 recorded events.

No event in this record carries a USGS link to NOAA tsunami information.
