2023-04-06 16:24:50 UTC (2023-04-06) · approx. 6:24 AM UTC-10 local
On April 6, 2023 at 16:24 UTC, a magnitude 2.3 shallow crustal earthquake struck 9 km WNW of Point MacKenzie, Alaska, at a depth of 26.2 km and coordinates 61.3941°, -150.1421°.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
