M5.2 Earthquake near Reykjanes Ridge — December 10, 2023
2023-12-10 01:31:23 UTC (2023-12-10) · approx. 11:31 PM UTC-2 local
On December 10, 2023 at 01:31 UTC, a magnitude 5.2 shallow crustal earthquake struck near Reykjanes Ridge, at a depth of 11.4 km and coordinates 56.6463°, -34.2904°. This earthquake was detected by 102 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 416, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
