M4.2 Earthquake near Reykjanes Ridge — January 28, 2024
2024-01-28 22:47:44 UTC (2024-01-28) · approx. 8:47 PM UTC-2 local
On January 28, 2024 at 22:47 UTC, a magnitude 4.2 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 59.5239°, -30.6723°.
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.
