M4.0 Earthquake in the Kazakhstan-Xinjiang border region — October 17, 2022
2022-10-17 20:48:44 UTC (2022-10-17) · approx. 1:48 AM UTC+5 local
On October 17, 2022 at 20:48 UTC, a magnitude 4.0 shallow crustal earthquake struck in the Kazakhstan-Xinjiang border region, at a depth of 51.4 km and coordinates 45.4000°, 81.3030°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
