A strong earthquake has struck Russia’s far eastern Kamchatka region, the regional governor says, prompting tsunami warnings in the region.

There were no reports of damage early on Friday (AEST), and the warnings do not stretch as far as Australia.

The US Geological Survey said the quake was measured at a magnitude of 7.8 and at a depth of 10 kilometres.

It said a series of aftershocks followed, measuring up to 5.8.

Russia’s emergencies ministry said the quake in the country’s far east had a magnitude of 7.2.

Governor Vladimir Solodov said all emergency services had been placed in a state of high readiness, but no damage had been reported.

A tsunami warning was issued for the eastern shore of the peninsula, which juts out into the Bering Sea and Pacific Ocean.

Solodov said tsunami waves as high as 1.5 metres were expected at various points along the coast and warned people to stay away from coastal areas.

Other officials reported tsunami waves of 30-62 centimetres along the peninsula’s coast.

“This morning is once again testing the resilience of Kamchatka residents,” Solodov wrote on the Telegram messaging app.

“Immediately after the earthquake, we began a rapid inspection of social institutions and residential buildings.”

A tsunami warning was also issued for parts of the Kuril island chain, north of Japan, the emergencies ministry said.

The US National Weather Service and Pacific Tsunami Warning Center issued a tsunami advisory for parts of Alaska following the quake, warning of strong currents, and a forecast of waves of up to three metres for parts of the Kamchatka coast.

Kamchatka is in a highly seismic area and there have been at least two quakes with a magnitude greater than 7 in the past week.

A powerful magnitude 8.8 earthquake – followed by an eruption of the region’s most active volcano – in the same area in late July triggered tsunamis and warnings across the Pacific.

The quake damaged buildings and injured several people in the remote Russian region. Tsunami waves of up to five metres partially flooded the port and a fish-processing plant in the remote town of Severo-Kurilsk, in the northern Kuril Islands, sweeping vessels from moorings.

Verified drone footage showed the town’s entire shoreline submerged, with taller buildings and some storage facilities surrounded by water.
