M3.2 Earthquake 217 km SE of Akutan, Alaska — October 18, 2024
2024-10-18 17:36:20 UTC (2024-10-18) · approx. 6:36 AM UTC-11 local
On October 18, 2024 at 17:36 UTC, a magnitude 3.2 shallow crustal earthquake struck 217 km SE of Akutan, Alaska, at a depth of 10.0 km and coordinates 52.6906°, -163.5659°.
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.
