2026-06-25 21:56:08 UTC (2026-06-25) · approx. 11:56 AM UTC-10 local
On June 25, 2026 at 21:56 UTC, a magnitude 3.4 intermediate depth earthquake struck 9 km WSW of Pedro Bay, Alaska, at a depth of 191.5 km and coordinates 59.7600°, -154.2670°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
