M4.2 Earthquake 192 km ESE of Ozernovskiy, Russia — June 26, 2026
2026-06-26 19:56:40 UTC (2026-06-26) · approx. 6:56 AM UTC+11 local
On June 26, 2026 at 19:56 UTC, a magnitude 4.2 shallow crustal earthquake struck 192 km ESE of Ozernovskiy, Russia, at a depth of 30.3 km and coordinates 51.1043°, 159.1886°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 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 5.3 mainshock that occurred 8 days ago 190 km SSE of Vilyuchinsk, 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 4.2 earthquake near Ozernovskiy, Russia?
The magnitude 4.2 earthquake that struck 192 km ESE of Ozernovskiy, Russia on June 26, 2026 at 19:56 UTC had a depth of 30.3 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 4.2 earthquakes can continue for several days and gradually diminish over time.
Is this the same earthquake as the M5.3 one earlier?
No. This magnitude 4.2 earthquake is an aftershock of the larger magnitude 5.3 mainshock that occurred earlier 190 km SSE of Vilyuchinsk, Russia. Aftershocks are smaller earthquakes triggered by stress changes from the mainshock.
