2025-02-17 19:32:16 UTC (2025-02-17) · approx. 8:32 AM UTC-11 local
On February 17, 2025 at 19:32 UTC, a magnitude 3.4 intermediate depth earthquake struck 44 km NE of King Cove, Alaska, at a depth of 114.6 km and coordinates 55.3834°, -161.8973°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
