2023-02-10 17:10:17 UTC (2023-02-10) · approx. 6:10 AM UTC-11 local
On February 10, 2023 at 17:10 UTC, a magnitude 3.5 shallow crustal earthquake struck near Fox Islands, Aleutian Islands, Alaska, at a depth of 68.0 km and coordinates 53.3260°, -167.5030°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
