M3.3 Earthquake 106 km SSW of Kaktovik, Alaska — October 13, 2024
2024-10-13 20:34:33 UTC (2024-10-13) · approx. 10:34 AM UTC-10 local
On October 13, 2024 at 20:34 UTC, a magnitude 3.3 shallow crustal earthquake struck 106 km SSW of Kaktovik, Alaska, at a depth of 5.7 km and coordinates 69.2656°, -144.7980°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
