2021-07-08 13:23:25 UTC (2021-07-08) · approx. 8:23 PM UTC+7 local
On July 8, 2021 at 13:23 UTC, a magnitude 5.1 shallow crustal earthquake struck near Southern Qinghai, China, at a depth of 10.0 km and coordinates 34.6768°, 97.9158°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
