2023-08-01 19:29:03 UTC (2023-08-01) · approx. 3:29 PM UTC-4 local
On August 1, 2023 at 19:29 UTC, a magnitude 4.3 shallow crustal earthquake struck near Davis Strait, at a depth of 10.0 km and coordinates 61.4163°, -59.7928°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
