2024-11-12 17:56:35 UTC (2024-11-12) · approx. 7:56 AM UTC-10 local
On November 12, 2024 at 17:56 UTC, a magnitude 2.1 shallow crustal earthquake struck 23 km SSW of Chenega, Alaska, at a depth of 17.2 km and coordinates 59.8626°, -148.1109°.
Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 21.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
