On March 27, 2021 at 06:59 UTC, a magnitude 5.2 shallow crustal earthquake struck 161 km ENE of Olonkinbyen, Svalbard and Jan Mayen, at a depth of 10.0 km and coordinates 71.3779°, -4.4720°.

Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
