2024-11-18 20:18:07 UTC (2024-11-18) · approx. 9:18 AM UTC-11 local
On November 18, 2024 at 20:18 UTC, a magnitude 3.0 shallow crustal earthquake struck 57 km SE of King Cove, Alaska, at a depth of 45.1 km and coordinates 54.7309°, -161.6387°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
