2021-06-22 21:11:28 UTC (2021-06-22) · approx. 4:11 AM UTC+7 local
On June 22, 2021 at 21:11 UTC, a magnitude 4.5 shallow crustal earthquake struck 55 km NNE of Jiangyou, China, at a depth of 10.0 km and coordinates 32.1968°, 105.0197°.
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.
