On May 27, 2025 at 00:39 UTC, a magnitude 5.1 shallow crustal earthquake struck 12 km WNW of Dehdasht, Iran, at a depth of 10.0 km and coordinates 30.8218°, 50.4361°. This earthquake was detected by 94 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 405, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 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.
