2024-06-12 18:40:21 UTC (2024-06-12) · approx. 6:40 AM UTC-12 local
On June 12, 2024 at 18:40 UTC, a magnitude 3.2 intermediate depth earthquake struck 31 km SW of Atka, Alaska, at a depth of 205.3 km and coordinates 51.9920°, -174.5153°.
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.
