USGS Records 7.8 Magnitude Earthquake in Russia’s Kamchatka; Aftershocks Keep Region on Alert

A powerful earthquake in Russia’s Kamchatka sparks tsunami alerts, aftershocks, and evacuation warnings; no casualties reported yet.

A powerful earthquake struck Russia’s Kamchatka Peninsula on Thursday night. The U.S. Geological Survey (USGS) recorded the tremor at 7.8 magnitude, with the epicenter located about 127–128 kilometers east of Petropavlovsk-Kamchatsky, the regional capital.

The quake struck at a shallow depth. USGS measured it at around 10 kilometers, while other reports placed it closer to 19.5 kilometers.

Different Readings on Magnitude

Russian officials gave a slightly different figure. The governor of Kamchatka announced the quake at 7.2 magnitude, while international monitors confirmed it as 7.8. Such differences are common in the early hours of major earthquakes, when agencies use different equipment and calculations.

Several aftershocks rattled the region after the earthquake. The strongest aftershock measured 5.8 magnitude, though no additional damage has been reported so far.

Tsunami Warnings Issued

Soon after the quake, the Russian Emergency Ministry issued a tsunami warning for parts of Kamchatka, asking people in coastal areas to move to higher ground.

In the United States, the Pacific Tsunami Warning Center and NOAA also issued tsunami advisories for parts of Alaska. These were precautionary measures, and most of them were later lifted or downgraded.

Waves and Sea Level Changes

Monitoring agencies reported sea level changes between 30 and 62 centimeters along some coasts. This confirmed that the quake triggered tsunami activity, but there were no large or destructive waves recorded.

Authorities in Kamchatka said there have been no major casualties or serious damage so far. Emergency teams remain on standby, and checks are still being carried out in remote coastal villages.

Why Kamchatka Is at Risk

Kamchatka lies in the Pacific Ring of Fire, one of the most active earthquake and volcanic zones in the world. The quake’s shallow depth of 10–20 kilometers increased the shaking on land and raised concerns about possible tsunami waves.

Officials Ask People to Stay Alert

Local officials have asked residents to remain careful, stay away from low-lying coastal areas until cleared, and follow safety instructions. International monitoring agencies continue to watch the region in case more seismic activity follows.
