Welcome to the Ring of Fire

Today we’re visiting the 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 3,680 metres above the Kamchatka Peninsula in far eastern Russia. These are just two of approximately 160 volcanoes that dot the region; 29 of them, including the Tolbachik complex, are still active. In fact, there is so much volcanic activity here that UNESCO calls the peninsula '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. The sparsely populated peninsula makes up the western edge of the Ring of Fire, a chain of volcanoes along the Pacific Ocean that account for 90 per cent of the world’s seismic activity. Wild, remote, and primal, Kamchatka is home to an abundance of wildlife: arctic fox, tundra wolves, reindeer, lynx, huge Chukotka moose, and the Kamchatka brown bear that can tip the scales at 1,400 pounds.
