Greater Tolbachik: Northern Fissure, Dead Forest, and the ‘Star’ nano-volcano with lava tunnels.
One of the unique natural phenomena of mid-Kamchatka is Severniy Proriv – Northern Fissure – a site where, as a result of a ‘fissure’, or crack, which formed during the 1975-76 big eruption of Tolbachik, three symmetrical cones of volcanic slag were left behind.
Such fissures are a rather rare volcanic phenomenon, but this one was predicted by volcanologists based on their constant observations of seismic activity around these parts in the mid-seventies: in 1975 the frequency of earthquakes around Tolbachik sharply increased – which meant that somewhere nearby there was lava bubbling up nearer and nearer the earth’s surface. So an expedition of volcanologists was dispatched there, who were lucky enough to observe the eruption from the very start. As a result this eruption was very well-documented and on the internet there’s a mass of information about it – admittedly, mostly in Russian. Today, the three cones formed by the Severniy Proriv – now collectively called Severniy Proriv (are you keeping up?:) – are still there, and they’re three mega-beauts:
