2023-11-18 17:51:36 UTC (2023-11-18) · approx. 6:51 AM UTC-11 local
On November 18, 2023 at 17:51 UTC, a magnitude 3.2 shallow crustal earthquake struck 183 km SW of Point Hope, Alaska, at a depth of 20.4 km and coordinates 67.4635°, -170.4208°.
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.
