2021-10-02 22:01:42 UTC (2021-10-02) · approx. 4:01 AM UTC+6 local
On October 2, 2021 at 22:01 UTC, a magnitude 4.2 shallow crustal earthquake struck 112 km WSW of Myitkyina, Myanmar, at a depth of 10.0 km and coordinates 24.9285°, 96.3949°.
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.
