2024-10-20 22:57:13 UTC (2024-10-20) · approx. 4:57 AM UTC+6 local
On October 20, 2024 at 22:57 UTC, a magnitude 4.1 shallow crustal earthquake struck 132 km E of Lhasa, China, at a depth of 10.0 km and coordinates 29.8315°, 92.4540°.
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.
