M3.3 Earthquake 91 km SSE of King Cove, Alaska — May 5, 2026
2026-05-05 06:56:36 UTC (3 days ago) · approx. 7:56 PM UTC-11 local
On May 5, 2026 at 06:56 UTC, a magnitude 3.3 shallow crustal earthquake struck 91 km SSE of King Cove, Alaska, at a depth of 1.8 km and coordinates 54.3450°, -161.6260°.
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.
