The Krasheninnikov Volcano erupted overnight on Sunday for the first time in 600 years in Russia’s far-east region of Kamchatka.
Scientists say it may be connected to the huge earthquake that hit off the coast of Russia last week.
"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 be connected to the earthquake on Wednesday that triggered tsunami warnings as far away as French Polynesia and Chile, and was followed by an eruption of Klyuchevskoy, the most active volcano on the Kamchatka Peninsula.
The Kamchatka branch of Russia's ministry for emergency services said that an ash plume rising up to 6,000 meters has been recorded following the volcano's eruption. The volcano itself stands at 1,856 meters.
Massive earthquakes rocks Russia
Krasheninnikov's eruption comes after an 8.8 magnitude earthquake was recorded off Russia's eastern coast. The Washington Post reported that the earthquake was the sixth most powerful tremor reported in the world.
On the day of the earthquake, another volcano erupted in the Kamchatka region. Klyuchevskoy, Eruarsia's largest volcano at standing at 4,750 meters, erupted on Wednesday.
The earthquake caused tsunami warnings across Russia, Japan, the West Coast of the US, and parts of South America.
