M3.2 Earthquake 44 km SW of Sand Point, Alaska — October 23, 2026
2026-10-23 02:49:47 UTC (1 hour ago) · approx. 3:49 PM UTC-11 local
On October 23, 2026 at 02:49 UTC, a magnitude 3.2 shallow crustal earthquake struck 44 km SW of Sand Point, Alaska, at a depth of 26.9 km and coordinates 55.0132°, -160.9015°.
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.
