M5.3 Earthquake near eastern Greenland — October 3, 2020
2020-10-03 13:22:47 UTC (2020-10-03) · approx. 11:22 AM UTC-2 local
On October 3, 2020 at 13:22 UTC, a magnitude 5.3 shallow crustal earthquake struck near eastern Greenland, at a depth of 10.0 km and coordinates 69.2919°, -29.8937°.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
