The Krasheninnikov Volcano in Kamchatka has erupted for the first time in 600 years and experts have connected it to the huge earthquake that rocked Russia's Far East last week, Russia's RIA state news agency reported on Sunday.

"This is the first historically confirmed eruption of Krasheninnikov Volcano in 600 years," RIA cited Olga Girina, head of the Kamchatka Volcanic Eruption Response Team, as saying.

She added that the eruption may have happened owing to the massive earthquake on Wednesday that triggered tsunami warnings as far away as French Polynesia and Chile.

The earthquake was also followed by an eruption of Klyuchevskoy, the most active volcano on the Kamchatka Peninsula.

On the Telegram channel of the Institute of Volcanology and Seismology, Girina said that Krasheninnikov's last lava effusion took place in 1463 - plus/minus 40 years - and no eruption has been known since.

The Kamchatka branch of Russia's ministry for emergency services said that an ash plume rising up to 6,000 meters (3.7 miles) has been recorded following the volcano's eruption.

The volcano itself stands at 1,856 metres.
