M3.1 Earthquake 88 km SE of Akutan, Alaska — July 26, 2026
2026-07-26 21:16:05 UTC (2026-07-26) · approx. 10:16 AM UTC-11 local
On July 26, 2026 at 21:16 UTC, a magnitude 3.1 shallow crustal earthquake struck 88 km SE of Akutan, Alaska, at a depth of 12.9 km and coordinates 53.6147°, -164.7481°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
