2023-06-12 15:35:33 UTC (2023-06-12) · approx. 5:35 AM UTC-10 local
On June 12, 2023 at 15:35 UTC, a magnitude 3.0 intermediate depth earthquake struck 41 km NW of Beluga, Alaska, at a depth of 87.7 km and coordinates 61.3641°, -151.6988°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
