2022-06-26 20:36:17 UTC (2022-06-26) · approx. 9:36 AM UTC-11 local
On June 26, 2022 at 20:36 UTC, a magnitude 3.4 shallow crustal earthquake struck 100 km SSE of King Cove, Alaska, at a depth of 38.6 km and coordinates 54.2876°, -161.5124°.
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.
