2024-06-17 19:07:21 UTC (2024-06-17) · approx. 6:07 AM UTC+11 local
On June 17, 2024 at 19:07 UTC, a magnitude 3.5 shallow crustal earthquake struck 156 km W of Attu Station, Alaska, at a depth of 10.0 km and coordinates 53.0158°, 170.8699°.
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.
