M3.1 Earthquake 22 km W of Chenega, Alaska — June 13, 2024
2024-06-13 17:50:38 UTC (2024-06-13) · approx. 7:50 AM UTC-10 local
On June 13, 2024 at 17:50 UTC, a magnitude 3.1 shallow crustal earthquake struck 22 km W of Chenega, Alaska, at a depth of 20.3 km and coordinates 60.0871°, -148.4180°.
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.
