M3.3 Earthquake 109 km N of Yakutat, Alaska — March 24, 2026
2026-03-24 20:55:49 UTC (2026-03-24) · approx. 11:55 AM UTC-9 local
On March 24, 2026 at 20:55 UTC, a magnitude 3.3 shallow crustal earthquake struck 109 km N of Yakutat, Alaska, at a depth of 5.0 km and coordinates 60.5206°, -139.5002°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
