2021-07-02 01:15:43 UTC (2021-07-02) · approx. 6:15 AM UTC+5 local
On July 2, 2021 at 01:15 UTC, a magnitude 4.7 shallow crustal earthquake struck 88 km SSE of Qapqal, China, at a depth of 10.0 km and coordinates 43.1001°, 81.5926°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
