2026-06-24 17:42:33 UTC (2026-06-24) · approx. 8:42 AM UTC-9 local
On June 24, 2026 at 17:42 UTC, a magnitude 3.1 shallow crustal earthquake struck 135 km E of Chalkyitsik, Alaska, at a depth of 10.3 km and coordinates 66.6636°, -140.6546°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
