2025-03-04 23:27:00 UTC (2025-03-04) · approx. 10:27 PM UTC-1 local
On March 4, 2025 at 23:27 UTC, a magnitude 4.5 shallow crustal earthquake struck 49 km NNE of Olonkinbyen, Svalbard and Jan Mayen, at a depth of 10.0 km and coordinates 71.3523°, -8.3478°. This earthquake was detected by 54 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
