M4.2 Earthquake in the Xinjiang-Xizang border region — August 30, 2023
2023-08-30 23:20:26 UTC (2023-08-30) · approx. 4:20 AM UTC+5 local
On August 30, 2023 at 23:20 UTC, a magnitude 4.2 shallow crustal earthquake struck in the Xinjiang-Xizang border region, at a depth of 10.0 km and coordinates 35.9411°, 81.5232°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
