2024-07-06 18:13:30 UTC (2024-07-06) · approx. 6:13 AM UTC+12 local
On July 6, 2024 at 18:13 UTC, a magnitude 4.1 intermediate depth earthquake struck near Rat Islands, Aleutian Islands, Alaska, at a depth of 108.6 km and coordinates 51.8859°, 178.3092°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
