On October 3, 2024 at 20:10 UTC, a magnitude 4.6 shallow crustal earthquake struck 223 km W of Olonkinbyen, Svalbard and Jan Mayen, at a depth of 10.0 km and coordinates 70.7182°, -14.7933°. This earthquake was detected by 36 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
