M4.5 Earthquake near Reykjanes Ridge — January 25, 2021
2021-01-25 20:26:37 UTC (2021-01-25) · approx. 6:26 PM UTC-2 local
On January 25, 2021 at 20:26 UTC, a magnitude 4.5 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 53.9112°, -35.1520°.
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.
