On January 8, 2025 at 20:58 UTC, a magnitude 4.6 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 53.1177°, -35.0754°. This earthquake was detected by 52 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
