On March 13, 2026 at 23:36 UTC, a magnitude 4.4 shallow crustal earthquake struck 95 km SSE of Vilyuchinsk, Russia, at a depth of 53.5 km and coordinates 52.1628°, 159.0237°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — 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 24 days ago 48 km SE of Vilyuchinsk, Russia. 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.

Common Questions

How strong was the magnitude 4.4 earthquake near Vilyuchinsk, Russia?

The magnitude 4.4 earthquake that struck 95 km SSE of Vilyuchinsk, Russia on March 13, 2026 at 23:36 UTC had a depth of 53.5 km. For context, this was a light earthquake commonly felt near the epicenter.

Were there aftershocks?

Aftershock activity is monitored continuously by the USGS. Aftershock sequences from magnitude 4.4 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 4.4 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 48 km SE of Vilyuchinsk, Russia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.

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.
