2024-12-26 21:31:53 UTC (2024-12-26) · approx. 9:31 AM UTC+12 local
On December 26, 2024 at 21:31 UTC, a magnitude 4.0 shallow crustal earthquake struck 267 km ESE of Attu Station, Alaska, at a depth of 35.0 km and coordinates 51.6886°, 176.6242°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
