2025-06-02 19:21:00 UTC (2025-06-02) · approx. 7:21 AM UTC+12 local
On June 2, 2025 at 19:21 UTC, a magnitude 3.3 intermediate depth earthquake struck 251 km W of Adak, Alaska, at a depth of 178.3 km and coordinates 52.1429°, 179.7347°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
