M4.7 Earthquake near Reykjanes Ridge — November 26, 2021
2021-11-26 19:29:40 UTC (2021-11-26) · approx. 5:29 PM UTC-2 local
On November 26, 2021 at 19:29 UTC, a magnitude 4.7 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 54.1944°, -35.0774°.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
