M3.0 Earthquake 103 km E of Atka, Alaska — June 24, 2024
2024-06-24 23:08:07 UTC (2024-06-24) · approx. 11:08 AM UTC-12 local
On June 24, 2024 at 23:08 UTC, a magnitude 3.0 shallow crustal earthquake struck 103 km E of Atka, Alaska, at a depth of 9.4 km and coordinates 52.3077°, -172.6905°.
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.
