M5.1 Earthquake north of Svalbard — September 6, 2021
2021-09-06 17:31:23 UTC (2021-09-06) · approx. 7:31 PM UTC+2 local
On September 6, 2021 at 17:31 UTC, a magnitude 5.1 shallow crustal earthquake struck north of Svalbard, at a depth of 10.0 km and coordinates 86.0617°, 32.9475°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
