This is a scientific measurement of an event that has already happened. It is not a warning, and it does not tell you what to do.

Internet connectivity at the time

Internet connectivity in Russia dropped 44 hours after this event, and stayed disrupted for about 1 hour.

From 18 Oct 2026 00:00 UTC to 18 Oct 2026 01:00 UTC. Detected by active probing — networks that stopped answering.

Internet outages have many causes — damaged cables, power failures, network maintenance and deliberate shutdowns among them. IODA detects the loss of connectivity and does not attribute it to anything. This is shown because it happened at the same time, not because one caused the other.

Measured by IODA, Georgia Institute of Technology.

What USGS has published since this earthquake

Shaking and its likely impact

USGS estimates fewer than 1,000 people were exposed to strong shaking or worse (intensity VI and above).

USGS's PAGER system gives a green alert for deaths, meaning a low likelihood of casualties; and a green alert for economic losses, meaning a low likelihood of damage. These are estimates from a model of the shaking and the population it reached, not a count.

USGS PAGER, automatic.

Reports of the shaking

USGS received 2 "Did You Feel It?" reports; the strongest shaking reported was intensity V (moderate).

How far the shaking reached

• Moderate shaking (intensity V) or more reached about 120 km from the epicentre at its farthest.
• Light shaking (intensity IV) or more reached at least 180 km from the epicentre, the edge of USGS's map.

USGS ShakeMap, automatic: an estimate built from seismic stations, felt reports and a model where there are neither. Distances are in a straight line from USGS's epicentre; the lines on the map above are USGS's contours, simplified. Shaking varies with the ground, so a place inside a line may have felt less or more.
