2024-06-25 14:57:34 UTC (2024-06-25) · approx. 3:57 AM UTC-11 local
On June 25, 2024 at 14:57 UTC, a magnitude 3.2 intermediate depth earthquake struck 39 km NNE of Cold Bay, Alaska, at a depth of 170.2 km and coordinates 55.5303°, -162.5727°.
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.
