2025-03-03 22:14:24 UTC (2025-03-03) · approx. 10:14 AM UTC-12 local
On March 3, 2025 at 22:14 UTC, a magnitude 3.0 intermediate depth earthquake struck 77 km ENE of Adak, Alaska, at a depth of 89.3 km and coordinates 52.1517°, -175.6032°.
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.
