A 7.0 magnitude earthquake hits off the eastern coast of Russia

A magnitude 7 earthquake struck off the shore of Russia's far-east Kamchatka Peninsula early Sunday morning local time, according to the regional seismic monitoring service.

According to the local ministry of emergencies, there were tremors felt all along the coast, even in Petropavlovsk-Kamchatsky, the seat of the province.

The regional office of Russia's ministry of emergencies in the Kamchatka area posted on Telegram, stating that "operational teams of rescuers and firefighters are inspecting buildings."

The USGS estimates that the epicenter was roughly 90 miles from Petropavlovsk-Kamchatsky, a seaside city home to about 181,000 people. The earthquake struck in the early hours of Sunday morning local time, at a depth of roughly 50 miles.

After first issuing a tsunami warning, the US National Tsunami Warning Center eventually declared that the threat had gone. There was never a tsunami alert from the local government.

A number of milder aftershocks were detected following the main earthquake, according to a website post by Russia's Unified Geophysical Service branch in Kamchatka.

Although there have been no confirmed reports of serious damage or casualties, authorities are keeping a tight eye on the situation.

The peninsula is located on the "Ring of Fire," a seismically active region that surrounds the majority of the Pacific Ocean. It is home to more than two dozen active volcanoes.
