M6.9 earthquake near Ozernovskiy, Russia

Map: the earthquake near Ozernovskiy, Russia, with plate boundaries

A magnitude 6.9 earthquake struck 76 km (47 mi) northeast of Ozernovskiy, Russia on Friday, October 16, 2026 at 03:35 UTC, at a depth of 135 km (84 mi), according to the U.S. Geological Survey. At this intermediate depth, shaking spreads out before it reaches the surface.

USGS’s PAGER impact estimate is GREEN: little or no damage expected.

Why here?

This earthquake struck about 225 km (140 mi) from the boundary between the North American and Pacific plates. Most earthquakes happen along plate boundaries like this one, where the pieces of Earth’s outer shell collide, pull apart or grind past each other. Stress builds up over years until the rock suddenly slips. At 135 km down, it most likely broke inside a plate that is sinking into the mantle beneath its neighbor, in what geologists call a subduction zone.

The red lines on the map are plate boundaries.

What kind of fault?

USGS’s analysis of the seismic waves shows it was a strike-slip earthquake: the two sides of the fault slid past each other sideways, like California’s San Andreas Fault.

Shaking and impact

The strongest shaking USGS estimates was intensity 6 on the Modified Mercalli scale: strong. About 14,003 people were exposed to moderate shaking or stronger (intensity 5 and up). USGS’s PAGER system estimates it most likely caused no deaths (90 percent probability). Early estimates are revised as reports come in.

How strong was it?

Magnitude is logarithmic: each whole step releases about 32 times more energy. This magnitude 6.9 released roughly the energy of 338 kilotons of TNT, about 23 times the Hiroshima atomic bomb. That is about 22,000 times the energy of a magnitude 4.0, a quake people nearby feel but that rarely causes damage. The strongest earthquake ever recorded, magnitude 9.5 in Chile in 1960, released about 7,900 times more than this one.

Aftershocks

In the first 10 days after it, USGS recorded no smaller earthquakes of magnitude 2.5 or more within 100 km (62 mi).

Outside the United States, USGS mainly lists quakes of about magnitude 4 and up, so smaller aftershocks there are undercounted.

Earthquake history here

Before this earthquake, USGS had recorded 227 earthquakes of magnitude 6 or larger within 300 km (186 mi) since 1900. The strongest:
