M3.0 Earthquake 184 km SSE of Akutan, Alaska — February 23, 2026
2026-02-23 22:04:48 UTC (2026-02-23) · approx. 11:04 AM UTC-11 local
On February 23, 2026 at 22:04 UTC, a magnitude 3.0 shallow crustal earthquake struck 184 km SSE of Akutan, Alaska, at a depth of 10.0 km and coordinates 52.6301°, -164.6062°.
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.
