On May 16, 2026 at 01:34 UTC, a magnitude 4.3 shallow crustal earthquake struck 298 km WNW of Longyearbyen, Svalbard and Jan Mayen, at a depth of 10.0 km and coordinates 79.7331°, 4.0880°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
