M4.1 Earthquake in the Russia-Mongolia border region — March 4, 2023
2023-03-04 13:41:47 UTC (2023-03-04) · approx. 8:41 PM UTC+7 local
On March 4, 2023 at 13:41 UTC, a magnitude 4.1 shallow crustal earthquake struck in the Russia-Mongolia border region, at a depth of 10.7 km and coordinates 51.0698°, 100.0627°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
