M4.2 Earthquake in the Iceland region — September 11, 2022
2022-09-11 23:50:19 UTC (2022-09-11) · approx. 10:50 PM UTC-1 local
On September 11, 2022 at 23:50 UTC, a magnitude 4.2 shallow crustal earthquake struck in the Iceland region, at a depth of 10.0 km and coordinates 66.5723°, -18.2098°.
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.
