M5.0 Earthquake 86 km SW of ??jj??b?d, Iran — February 22, 2023
2023-02-22 01:11:07 UTC (2023-02-22) · approx. 5:11 AM UTC+4 local
On February 22, 2023 at 01:11 UTC, a magnitude 5.0 shallow crustal earthquake struck 86 km SW of ??jj??b?d, Iran, at a depth of 10.0 km and coordinates 27.7531°, 55.2852°. This earthquake was detected by 256 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, 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.

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.
