2025-06-05 21:20:20 UTC (2025-06-05) · approx. 9:20 AM UTC-12 local
On June 5, 2025 at 21:20 UTC, a magnitude 3.2 shallow crustal earthquake struck 57 km WSW of Adak, Alaska, at a depth of 13.0 km and coordinates 51.7038°, -177.4236°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
