2024-06-01 19:17:55 UTC (2024-06-01) · approx. 7:17 AM UTC-12 local
On June 1, 2024 at 19:17 UTC, a magnitude 4.0 shallow crustal earthquake struck 176 km WSW of Adak, Alaska, at a depth of 40.5 km and coordinates 51.1392°, -178.8805°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
