2021-08-28 19:20:46 UTC (2021-08-28) · approx. 1:20 AM UTC+6 local
On August 28, 2021 at 19:20 UTC, a magnitude 4.4 shallow crustal earthquake struck 119 km ENE of Sishilichengzi, China, at a depth of 10.0 km and coordinates 42.2424°, 87.8657°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
