M4.5 Earthquake in the Iceland region — September 26, 2026
2026-09-26 02:52:55 UTC (1 hour ago) · approx. 1:52 AM UTC-1 local
On September 26, 2026 at 02:52 UTC, a magnitude 4.5 shallow crustal earthquake struck in the Iceland region, at a depth of 10.0 km and coordinates 68.8565°, -16.9554°. This earthquake was detected by 39 seismic stations with good location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — 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.

Common Questions
How strong was the magnitude 4.5 earthquake in the Iceland region?
The magnitude 4.5 earthquake that struck in the Iceland region on September 26, 2026 at 02:52 UTC had a depth of 10.0 km. For context, this was a light earthquake commonly felt near the epicenter.
Where did the earthquake occur?

Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.5 earthquakes can continue for several days and gradually diminish over time.
Has Iceland had earthquakes this big before?
The largest recorded earthquake in Iceland was the M6.6 South Iceland earthquake of June 17, 2000. Today's magnitude 4.5 event is significantly smaller than that historical record.
