2023-07-27 20:51:29 UTC (2023-07-27) · approx. 11:51 AM UTC-9 local
On July 27, 2023 at 20:51 UTC, a magnitude 3.7 shallow crustal earthquake struck 89 km ENE of Dawson City, Canada, at a depth of 5.5 km and coordinates 64.3108°, -137.6937°.
Physical scale: An earthquake of magnitude 3.7 releases seismic energy equivalent to roughly 5.4 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 215 m — a useful intuition for the size of the slip patch on the fault.
