On October 12, 2025 at 03:13 UTC, a magnitude 4.9 shallow crustal earthquake struck in the Svalbard region, at a depth of 10.0 km and coordinates 76.0756°, 7.4191°. This earthquake was detected by 60 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 km — a useful intuition for the size of the slip patch on the fault.

Common Questions

How strong was the magnitude 4.9 earthquake in the Svalbard region?

The magnitude 4.9 earthquake that struck in the Svalbard region on October 12, 2025 at 03:13 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 4.9 earthquakes can continue for several days and gradually diminish over time.

What should I do after an earthquake?

If you were in the affected area: check yourself and others for injuries, inspect your home for damage, and be prepared for aftershocks. For detailed guidance, see our earthquake safety guide and emergency planning resources.
