2023-11-08 21:28:55 UTC (2023-11-08) · approx. 11:28 AM UTC-10 local
On November 8, 2023 at 21:28 UTC, a magnitude 3.5 intermediate depth earthquake struck 60 km WNW of Nanwalek, Alaska, at a depth of 98.3 km and coordinates 59.5248°, -152.9390°.
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.
