The sudden activity follows a strong earthquake in the area on Saturday.
At one of the volcanoes, Klyuchevskaya Sopka, up to ten explosions an hour were recorded on Sunday, and lava and ash are also pouring out of the other volcano, Shivelyuch, according to the Institute of Volcanology of the Russian Academy of Sciences.
At 4,754 meters, Klyutchevskaya Sopka is the highest volcano on the Eurasian continent.
There are about 30 active volcanoes on the Kamchatka Peninsula, which is one of the areas in the world where geothermal energy is most concentrated.
The Kamchatka Peninsula in the Pacific Ocean is sparsely populated and the two volcanoes are located 450 kilometers from the peninsula’s largest city, Petropavlovsk-Kamchatsky. In the middle between the two volcanoes is a dense settlement with 5,000 inhabitants, Klyutshi.
