M3.5 Earthquake 134 km SW of Point Hope, Alaska — December 19, 2023
2023-12-19 16:02:24 UTC (2023-12-19) · approx. 5:02 AM UTC-11 local
On December 19, 2023 at 16:02 UTC, a magnitude 3.5 shallow crustal earthquake struck 134 km SW of Point Hope, Alaska, at a depth of 10.1 km and coordinates 67.4096°, -168.7410°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
