M4.1 Earthquake near Reykjanes Ridge — March 11, 2025
2025-03-11 23:41:32 UTC (2025-03-11) · approx. 9:41 PM UTC-2 local
On March 11, 2025 at 23:41 UTC, a magnitude 4.1 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 10.0 km and coordinates 52.4576°, -32.9639°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
