2025-08-15 22:17:27 UTC (2025-08-15) · approx. 12:17 PM UTC-10 local
On August 15, 2025 at 22:17 UTC, a magnitude 2.4 intermediate depth earthquake struck 55 km ENE of Pedro Bay, Alaska, at a depth of 136.3 km and coordinates 59.9923°, -153.2055°.
Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 60.0 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 27 m — a useful intuition for the size of the slip patch on the fault.
