M3.0 Earthquake 32 km ENE of Sand Point, Alaska — October 5, 2022
2022-10-05 20:35:59 UTC (2022-10-05) · approx. 9:35 AM UTC-11 local
On October 5, 2022 at 20:35 UTC, a magnitude 3.0 shallow crustal earthquake struck 32 km ENE of Sand Point, Alaska, at a depth of 10.0 km and coordinates 55.4024°, -160.0032°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
