2024-06-22 23:09:47 UTC (2024-06-22) · approx. 11:09 AM UTC-12 local
On June 22, 2024 at 23:09 UTC, a magnitude 3.0 intermediate depth earthquake struck 83 km ESE of Atka, Alaska, at a depth of 86.6 km and coordinates 51.8301°, -173.1415°.
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.
