2024-10-17 16:37:15 UTC (2024-10-17) · approx. 6:37 AM UTC-10 local
On October 17, 2024 at 16:37 UTC, a magnitude 3.1 shallow crustal earthquake struck 33 km SW of Akhiok, Alaska, at a depth of 40.6 km and coordinates 56.7266°, -154.5515°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
