On August 11, 2026 at 14:28 UTC, a magnitude 3.4 shallow crustal earthquake struck 41 km SSW of Karluk, Alaska, at a depth of 41.0 km and coordinates 57.2510°, -154.8230°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
