On February 12, 2026 at 16:45 UTC, a magnitude 5.4 shallow crustal earthquake struck 151 km SSE of Kuril’sk, Russia, at a depth of 30.3 km and coordinates 44.0306°, 148.7822°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 106 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 449, placing it among routine seismic activity. The nearest populated place is Kuril'sk (population 1,719).

Physical scale: An earthquake of magnitude 5.4 releases seismic energy equivalent to roughly 2 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 3.2 km — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Russia, a region characterized by the Kuril-Kamchatka subduction zone on the northwestern Pacific Ring of Fire. The nearest mapped fault system is the Kuril-Kamchatka Trench. View all earthquakes in Russia.

Common Questions

How strong was the magnitude 5.4 earthquake near Kuril’sk, Russia?

The magnitude 5.4 earthquake that struck 151 km SSE of Kuril’sk, Russia on February 12, 2026 at 16:45 UTC had a depth of 30.3 km. For context, this was a moderate earthquake that could be widely felt.

Where did the earthquake occur?

The earthquake epicenter was located at 44.0306°, 148.7822°, which is 151 km SSE of Kuril’sk, Russia. The nearest populated place is Kuril'sk (population 1,719). View all earthquakes in Russia.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 5.4 earthquakes can continue for days to weeks and gradually diminish over time.

Has Russia had earthquakes this big before?

The largest recorded earthquake in Russia was the M9.0 Kamchatka earthquake of November 4, 1952. Today's magnitude 5.4 event is significantly smaller than that historical record.

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.
