Aftershock of the M5.4 mainshock.
On June 13, 2026 at 20:14 UTC, a magnitude 4.8 shallow crustal earthquake struck 117 km S of Akureyri, Iceland, at a depth of 10.0 km and coordinates 64.6396°, -17.6981°. This earthquake was detected by 82 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
This earthquake is part of an ongoing aftershock sequence following the magnitude 5.4 mainshock that occurred 21 days ago 113 km S of Akureyri, Iceland. Since the mainshock, the USGS has recorded 0 aftershocks in this area. Aftershock activity is expected to continue for days to weeks as stresses on surrounding faults redistribute.
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 4.8 earthquake near Akureyri, Iceland?
The magnitude 4.8 earthquake that struck 117 km S of Akureyri, Iceland on June 13, 2026 at 20:14 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?
The earthquake epicenter was located at 64.6396°, -17.6981°, which is 117 km S of Akureyri, Iceland. View all earthquakes in Iceland.
Were there aftershocks?
Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.8 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.4 one earlier?
No. This magnitude 4.8 earthquake is an aftershock of the larger magnitude 5.4 mainshock that occurred earlier 113 km S of Akureyri, Iceland. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
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 4.8 event is significantly smaller than that historical record.
