2024-10-09 21:33:29 UTC (2024-10-09) · approx. 11:33 AM UTC-10 local
On October 9, 2024 at 21:33 UTC, a magnitude 3.2 shallow crustal earthquake struck 99 km SSW of Kaktovik, Alaska, at a depth of 18.1 km and coordinates 69.3455°, -144.8236°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
