2024-06-02 22:57:00 UTC (2024-06-02) · approx. 10:57 AM UTC+12 local
On June 2, 2024 at 22:57 UTC, a magnitude 3.9 shallow crustal earthquake struck 142 km ESE of Attu Station, Alaska, at a depth of 35.2 km and coordinates 52.1603°, 174.9617°.
Physical scale: An earthquake of magnitude 3.9 releases seismic energy equivalent to roughly 11 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 296 m — a useful intuition for the size of the slip patch on the fault.
