On June 11, 2026 at 01:27 UTC, a magnitude 4.1 shallow crustal earthquake struck 184 km SE of Petropavlovsk-Kamchatsky, Russia, at a depth of 35.0 km and coordinates 51.9600°, 160.6456°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 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 1 day ago 163 km ESE of Petropavlovsk-Kamchatsky, Russia. Since the mainshock, the USGS has recorded 3 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 4.1 earthquake near Petropavlovsk-Kamchatsky, Russia?

The magnitude 4.1 earthquake that struck 184 km SE of Petropavlovsk-Kamchatsky, Russia on June 11, 2026 at 01:27 UTC had a depth of 35.0 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 4.1 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 4.1 earthquake is an aftershock of the larger magnitude 5.2 mainshock that occurred earlier 163 km ESE of Petropavlovsk-Kamchatsky, 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.
