M4.7 Earthquake north of Svalbard — May 10, 2023
2023-05-10 22:58:27 UTC (2023-05-10) · approx. 12:58 AM UTC+2 local
On May 10, 2023 at 22:58 UTC, a magnitude 4.7 shallow crustal earthquake struck north of Svalbard, at a depth of 10.0 km and coordinates 86.2658°, 34.1213°. This earthquake was detected by 114 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
