2026-04-08 21:29:09 UTC (2026-04-08) · approx. 7:29 PM UTC-2 local
On April 8, 2026 at 21:29 UTC, a magnitude 4.5 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 52.9630°, -35.3801°. This earthquake was detected by 64 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
