2026-06-05 15:38:10 UTC (2 hours ago) · approx. 6:38 PM UTC+3 local
On June 5, 2026 at 15:38 UTC, a magnitude 4.8 shallow crustal earthquake struck 66 km W of Fīrūzābād, Iran, at a depth of 10.0 km and coordinates 28.9088°, 51.8960°. This earthquake was detected by 72 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
