2022-02-20 23:09:50 UTC (2022-02-20) · approx. 5:09 AM UTC+6 local
On February 20, 2022 at 23:09 UTC, a magnitude 4.5 shallow crustal earthquake struck 107 km WSW of Qamdo, China, at a depth of 10.0 km and coordinates 30.7466°, 96.1421°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
