2023-10-30 22:24:09 UTC (2023-10-30) · approx. 4:24 AM UTC+6 local
On October 30, 2023 at 22:24 UTC, a magnitude 4.3 shallow crustal earthquake struck 157 km E of Aqqan, China, at a depth of 10.0 km and coordinates 36.5324°, 83.7227°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
