M4.7 Earthquake Vilyuchinsk, Russia

On June 3, 2026 at 18:09 UTC, a magnitude 4.7 shallow crustal earthquake struck 181 km SSE of Vilyuchinsk, Russia, at a depth of 25.7 km and coordinates 51.4846°, 159.6419°. This earthquake was detected by 120 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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 5.2 mainshock that occurred 2 hours ago 202 km SSE of Vilyuchinsk, Russia. Since the mainshock, the USGS has recorded 1 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 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 4.7 earthquake near Vilyuchinsk, Russia?

The magnitude 4.7 earthquake that struck 181 km SSE of Vilyuchinsk, Russia on June 3, 2026 at 18:09 UTC had a depth of 25.7 km. For context, this was a light earthquake commonly felt near the epicenter.

Where did the earthquake occur?

The earthquake epicenter was located at 51.4846°, 159.6419°, which is 181 km SSE of Vilyuchinsk, Russia. View all earthquakes in Russia.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.7 earthquakes can continue for several days and gradually diminish over time.

Is this the same earthquake as the M5.2 one earlier?

No. This magnitude 4.7 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 202 km SSE of Vilyuchinsk, Russia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

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 4.7 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.
