M5.4 Earthquake 31 km SE of Masjed Soleymān, Iran — December 5, 2024
2024-12-05 04:02:40 UTC (2024-12-05) · approx. 7:02 AM UTC+3 local
Felt by 28 people across nearby locations. Maximum shaking intensity MMI 6.2 (very strong).
On December 5, 2024 at 04:02 UTC, a magnitude 5.4 shallow crustal earthquake struck 31 km SE of Masjed Soleymān, Iran, at a depth of 17.0 km and coordinates 31.7601°, 49.5690°. The earthquake was reported felt by 28 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 6.2 (very strong). The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 141 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 462, placing it among routine seismic activity. The nearest populated place is Izeh (population 0).
Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 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.

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.4 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 5.4 event is significantly smaller than that historical record.
