On October 24, 2023 at 22:19 UTC, a magnitude 5.2 shallow crustal earthquake struck 106 km S of Akureyri, Iceland, at a depth of 10.0 km and coordinates 64.7362°, -17.7358°. This earthquake was detected by 155 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 417, 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.
The epicenter is located in Iceland, a region characterized by the Mid-Atlantic Ridge, where the North American and Eurasian plates diverge at 18-25 mm per year, amplified by the Iceland mantle plume. The nearest mapped fault system is the Mid-Atlantic Ridge. View all earthquakes in Iceland.
