The Russian Coast’s strongest earthquake since 1952 provided enough energy for six volcanoes adjacent to the Ring of Fire to spout off. Another could be imminent.

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

The overnight eruption of the Krasheninnikov Volcano in Kamchatka, its first in 600 years, may be connected to the huge earthquake that rocked Russia’s Far East last week, Russia’s RIA state news agency and scientists reported on Sunday.
