On May 3, 2025 at 23:53 UTC, a magnitude 3.8 shallow crustal earthquake struck 20 km N of Simav, Turkey, at a depth of 9.9 km and coordinates 39.2694°, 28.9966°.
Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
