2024-08-09 21:17:56 UTC (2024-08-09) · approx. 8:17 AM UTC+11 local
On August 9, 2024 at 21:17 UTC, a magnitude 4.0 shallow crustal earthquake struck 122 km SSW of Ust’-Kamchatsk Staryy, Russia, at a depth of 60.3 km and coordinates 55.1712°, 161.9324°.
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.
