2024-08-09 21:41:12 UTC (2024-08-09) · approx. 6:41 PM UTC-3 local
On August 9, 2024 at 21:41 UTC, a magnitude 4.4 shallow crustal earthquake struck 89 km NE of Nanortalik, Greenland, at a depth of 10.0 km and coordinates 60.6718°, -44.0243°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
