On May 10, 2021 at 19:59 UTC, a magnitude 4.4 shallow crustal earthquake struck 298 km WNW of Longyearbyen, Svalbard and Jan Mayen, at a depth of 10.0 km and coordinates 79.6442°, 3.8311°.
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.
