2024-07-09 22:20:45 UTC (2024-07-09) · approx. 11:20 PM UTC+1 local
On July 9, 2024 at 22:20 UTC, a magnitude 5.0 shallow crustal earthquake struck 256 km SW of Longyearbyen, Svalbard and Jan Mayen, at a depth of 10.0 km and coordinates 76.7414°, 7.5307°. This earthquake was detected by 199 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
