2024-08-09 21:16:38 UTC (2024-08-09) · approx. 11:16 AM UTC-10 local
On August 9, 2024 at 21:16 UTC, a magnitude 3.1 shallow crustal earthquake struck 33 km SE of Minto, Alaska, at a depth of 17.1 km and coordinates 64.9193°, -148.9112°.
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.
