2025-04-29 21:06:55 UTC (2025-04-29) · approx. 11:06 AM UTC-10 local
On April 29, 2025 at 21:06 UTC, a magnitude 3.0 intermediate depth earthquake struck 41 km NE of Pedro Bay, Alaska, at a depth of 147.2 km and coordinates 60.0111°, -153.5178°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
