2025-06-14 15:53:37 UTC (2025-06-14) · approx. 5:53 AM UTC-10 local
On June 14, 2025 at 15:53 UTC, a magnitude 3.0 shallow crustal earthquake struck 275 km ESE of Chiniak, Alaska, at a depth of 10.0 km and coordinates 56.6716°, -148.0637°.
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.
