On January 11, 2021 at 23:02 UTC, a magnitude 5.0 shallow crustal earthquake struck 25 km WSW of Turt, Mongolia, at a depth of 10.0 km and coordinates 51.4379°, 100.3097°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
