2024-05-28 19:54:58 UTC (2024-05-28) · approx. 7:54 AM UTC-12 local
On May 28, 2024 at 19:54 UTC, a magnitude 3.2 intermediate depth earthquake struck 35 km WNW of Atka, Alaska, at a depth of 146.8 km and coordinates 52.3703°, -174.6314°.
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.
