2023-09-28 23:15:44 UTC (2023-09-28) · approx. 7:15 PM UTC-4 local
On September 28, 2023 at 23:15 UTC, a magnitude 4.1 shallow crustal earthquake struck near Davis Strait, at a depth of 10.0 km and coordinates 61.3042°, -59.4559°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
