M3.0 Earthquake 102 km SSW of Kaktovik, Alaska — October 10, 2024
2024-10-10 21:21:35 UTC (2024-10-10) · approx. 11:21 AM UTC-10 local
On October 10, 2024 at 21:21 UTC, a magnitude 3.0 shallow crustal earthquake struck 102 km SSW of Kaktovik, Alaska, at a depth of 1.1 km and coordinates 69.3163°, -144.8616°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
