On May 5, 2026 at 20:53 UTC, a magnitude 4.9 shallow crustal earthquake struck 32 km SSW of Sarpol-e Z̄ahāb, Iran, at a depth of 10.0 km and coordinates 34.1806°, 45.7647°. This earthquake was detected by 61 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Iran, a region characterized by the Zagros fold-and-thrust belt, where the Arabian Plate collides with Eurasia at 20-25 mm per year. The nearest mapped fault system is the Zagros Fault. View all earthquakes in Iran.

Has Iran had earthquakes this big before?
The largest recorded earthquake in Iran was the M7.8 Tabas earthquake of September 16, 1978. Today's magnitude 4.9 event is significantly smaller than that historical record.
What should I do after an earthquake?
