2022-06-07 15:59:53 UTC (2022-06-07) · approx. 2:59 AM UTC+11 local
On June 7, 2022 at 15:59 UTC, a magnitude 4.3 shallow crustal earthquake struck 287 km WNW of Attu Station, Alaska, at a depth of 10.0 km and coordinates 54.0517°, 169.3508°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
