2026-10-19 14:44:24 UTC (4 hours ago) · approx. 1:44 PM UTC-1 local
On October 19, 2026 at 14:44 UTC, a magnitude 5.3 shallow crustal earthquake struck 116 km WNW of Höfn, Iceland, at a depth of 10.0 km and coordinates 64.5774°, -17.5136°. This earthquake was detected by 95 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 432, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.3 releases seismic energy equivalent to roughly 1 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.7 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.
