2023-05-15 22:11:55 UTC (2023-05-15) · approx. 11:11 AM UTC-11 local
On May 15, 2023 at 22:11 UTC, a magnitude 3.2 intermediate depth earthquake struck 61 km SSW of Nelson Lagoon, Alaska, at a depth of 125.7 km and coordinates 55.5218°, -161.6839°.
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.
