2025-03-23 22:45:21 UTC (2025-03-23) · approx. 1:45 AM UTC+3 local
On March 23, 2025 at 22:45 UTC, a magnitude 4.0 shallow crustal earthquake struck 13 km NW of Yasuj, Iran, at a depth of 10.0 km and coordinates 30.7576°, 51.4904°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
