2024-10-04 08:58:49 UTC (2024-10-04) · approx. 7:58 AM UTC-1 local
On October 4, 2024 at 08:58 UTC, a magnitude 4.8 shallow crustal earthquake struck 215 km W of Olonkinbyen, Svalbard and Jan Mayen, at a depth of 10.0 km and coordinates 70.6467°, -14.5171°. This earthquake was detected by 49 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
