On August 21, 2024 at 21:47 UTC, a magnitude 4.3 shallow crustal earthquake struck 154 km E of Petropavlovsk-Kamchatsky, Russia, at a depth of 48.7 km and coordinates 52.8146°, 160.8938°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
