M4.6 Earthquake in the Tajikistan-Xinjiang border region — August 2, 2021
2021-08-02 22:47:47 UTC (2021-08-02) · approx. 3:47 AM UTC+5 local
On August 2, 2021 at 22:47 UTC, a magnitude 4.6 shallow crustal earthquake struck in the Tajikistan-Xinjiang border region, at a depth of 10.0 km and coordinates 38.2622°, 73.1776°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
