On October 2, 2025 at 20:35 UTC, a magnitude 5.0 shallow crustal earthquake struck 78 km NE of Ardestān, Iran, at a depth of 10.0 km and coordinates 33.8719°, 52.9715°. This earthquake was detected by 110 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.

Common Questions

How strong was the magnitude 5.0 earthquake near Ardestān, Iran?

The magnitude 5.0 earthquake that struck 78 km NE of Ardestān, Iran on October 2, 2025 at 20:35 UTC had a depth of 10.0 km. For context, this was a moderate earthquake that could be widely felt.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.0 earthquakes can continue for days to weeks and gradually diminish over time.

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 5.0 event is significantly smaller than that historical record.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
