On September 5, 2024 at 18:12 UTC, a magnitude 5.5 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 52.6274°, -34.3303°.0 The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 118 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 466, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.5 releases seismic energy equivalent to roughly 3 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.8 km — a useful intuition for the size of the slip patch on the fault.
