M3.7 Earthquake 67 km SSW of Haines Junction, Canada — January 27, 2023
2023-01-27 20:38:18 UTC (2023-01-27) · approx. 11:38 AM UTC-9 local
On January 27, 2023 at 20:38 UTC, a magnitude 3.7 shallow crustal earthquake struck 67 km SSW of Haines Junction, Canada, at a depth of 9.6 km and coordinates 60.2325°, -138.1385°.
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.
