M3.5 Earthquake 198 km SSE of Atka, Alaska — June 5, 2024
2024-06-05 21:33:15 UTC (2024-06-05) · approx. 9:33 AM UTC-12 local
On June 5, 2024 at 21:33 UTC, a magnitude 3.5 shallow crustal earthquake struck 198 km SSE of Atka, Alaska, at a depth of 10.0 km and coordinates 50.5094°, -173.2869°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
