M4.2 Earthquake in the Iceland region — January 29, 2025
2025-01-29 21:19:13 UTC (2025-01-29) · approx. 8:19 PM UTC-1 local
On January 29, 2025 at 21:19 UTC, a magnitude 4.2 shallow crustal earthquake struck in the Iceland region, at a depth of 10.0 km and coordinates 68.8738°, -16.9161°.
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.
