2021-08-03 23:24:03 UTC (2021-08-03) · approx. 2:24 PM UTC-9 local
On August 3, 2021 at 23:24 UTC, a magnitude 3.0 shallow crustal earthquake struck 128 km NNE of Dawson City, Canada, at a depth of 16.1 km and coordinates 65.0811°, -138.1981°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
