2026-05-03 12:15:24 UTC (8 hours ago) · approx. 12:15 AM UTC+12 local
On May 3, 2026 at 12:15 UTC, a magnitude 3.5 shallow crustal earthquake struck 282 km SE of Attu Station, Alaska, at a depth of 0.0 km and coordinates 51.3360°, 176.5070°.
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.
