Among the active volcanic eruptions was the Krasheninnikov volcano, a previously at least 400-year-dormant volcano.

Largest active volcano in the northern hemisphere began erupting on Wednesday afternoon following the huge earthquake in Russia's far east.

However, less than a week later another major volcano in the area spewed debris in a rare eruption not seen for over 600 years. "This is the first historically confirmed eruption of Krasheninnikov Volcano in 600 years," Russian state news agency RIA cited Olga Girina, head of the Kamchatka Volcanic Eruption Response Team, as saying, via SkyNews.
