M4.9 Earthquake in the Svalbard region — October 12, 2025
2025-10-12 03:13:11 UTC (2025-10-12) · approx. 3:13 AM UTC+0 local
On October 12, 2025 at 03:13 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Svalbard region, at a depth of 10.0 km and coordinates 76.0756°, 7.4191°. This earthquake was detected by 60 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.
