2024-07-18 20:00:47 UTC (2024-07-18) · approx. 7:00 AM UTC+11 local
On July 18, 2024 at 20:00 UTC, a magnitude 4.2 shallow crustal earthquake struck 170 km S of Ust’-Kamchatsk Staryy, Russia, at a depth of 32.9 km and coordinates 54.7237°, 162.0059°.
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.
