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.

Regional authorities in one region declared an emergency after a tsunami hit the Kuril Islands, and the Kamchatka Peninsula was watching for volcanic activity.

At 11:24 am local time on July 30, 2025, a powerful earthquake struck offshore of the Kamchatka Peninsula, triggering a tsunami in the Pacific Ocean.
