M3.0 Earthquake 13 km WSW of Akutan, Alaska — October 23, 2024
2024-10-23 22:39:55 UTC (2024-10-23) · approx. 11:39 AM UTC-11 local
On October 23, 2024 at 22:39 UTC, a magnitude 3.0 shallow crustal earthquake struck 13 km WSW of Akutan, Alaska, at a depth of 9.4 km and coordinates 54.1035°, -165.9781°.
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.
