2026-09-20 00:58:14 UTC (1 hour ago) · approx. 10:58 PM UTC-2 local
On September 20, 2026 at 00:58 UTC, a magnitude 5.3 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 57.1211°, -33.5459°. This earthquake was detected by 77 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 km — a useful intuition for the size of the slip patch on the fault.
