M3.4 Earthquake 44 km E of Atka, Alaska — November 15, 2024
2024-11-15 22:48:42 UTC (2024-11-15) · approx. 10:48 AM UTC-12 local
On November 15, 2024 at 22:48 UTC, a magnitude 3.4 shallow crustal earthquake struck 44 km E of Atka, Alaska, at a depth of 12.0 km and coordinates 52.1698°, -173.5468°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
