2025-06-01 21:34:08 UTC (2025-06-01) · approx. 11:34 AM UTC-10 local
On June 1, 2025 at 21:34 UTC, a magnitude 2.7 shallow crustal earthquake struck 84 km WSW of Karluk, Alaska, at a depth of 69.8 km and coordinates 57.2177°, -155.6938°.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 169 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 44 m — a useful intuition for the size of the slip patch on the fault.
