On March 31, 2021 at 00:01 UTC, a magnitude 5.2 shallow crustal earthquake struck 41 km SSW of Turt, Mongolia, at a depth of 14.2 km and coordinates 51.1814°, 100.3687°.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
