Welcome to the Ring of Fire

Today we’re visiting a pair of volcanoes known as Tolbachik, the flat-topped Plosky (Flat) Tolbachik on the left of our image, and the majestic Ostry (Sharp) Tolbachik on the right, which soars 12,080ft above the Kamchatka Peninsula in the Russian Far East. These are just two of around 160 volcanoes in the region; 29 of them, including the Tolbachik complex, are still active. Unesco describes the peninsula as one of the most outstanding volcanic regions in the world and has designated it a World Heritage Site.

The Kamchatka Peninsula juts out from the Russian mainland between the Sea of Okhotsk to the east and the Pacific Ocean and Bering Sea to the west. Sparsely populated, it makes up the western edge of the Ring of Fire, a chain of volcanoes along the Pacific Ocean that account for 90% of the world’s seismic activity. Wild and remote, Kamchatka is home to an abundance of wildlife: arctic fox, tundra wolves, reindeer, lynx, huge Chukotka moose and the Kamchatka brown bear that can weigh up to 100 stone.
