2023-09-13 02:33:08 UTC (2023-09-13) · approx. 1:33 AM UTC-1 local
On September 13, 2023 at 02:33 UTC, a magnitude 5.1 shallow crustal earthquake struck 220 km W of Olonkinbyen, Svalbard and Jan Mayen, at a depth of 10.0 km and coordinates 70.6481°, -14.6524°. This earthquake was detected by 101 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.
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.
