2022-09-26 20:32:22 UTC (2022-09-26) · approx. 6:32 PM UTC-2 local
On September 26, 2022 at 20:32 UTC, a magnitude 4.2 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 53.9877°, -35.2777°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
