M3.0 Earthquake 63 km S of Ivanof Bay, Alaska — June 11, 2025
2025-06-11 12:16:44 UTC (2025-06-11) · approx. 1:16 AM UTC-11 local
On June 11, 2025 at 12:16 UTC, a magnitude 3.0 shallow crustal earthquake struck 63 km S of Ivanof Bay, Alaska, at a depth of 19.4 km and coordinates 55.3405°, -159.3061°.
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.
