2025-06-04 18:24:18 UTC (2025-06-04) · approx. 8:24 AM UTC-10 local
On June 4, 2025 at 18:24 UTC, a magnitude 3.2 intermediate depth earthquake struck 15 km WSW of Salamatof, Alaska, at a depth of 86.9 km and coordinates 60.5713°, -151.5954°.0
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.
