In the area of the forest and tundra, where bears grazed calmly on red whortleberries, on July 6 , 1975 , a fissure opened in Tolbachik Valley and a new volcano commenced its short life. It is called the Big Cleft Tolbachik eruption.

It is considered one of the largest basalt eruptions and it was included in a list of six the most powerful cleft eruptions ever happened on Earth.

In sequence, new clefts evolved one after another, and as a result four new cones of Tolbachik Volcanoes were formed. An enormous territory around them turned into a burnt desert, the forest captured by the ash fall dried off to the root. Lakes and rivers disappeared. Those animals that had survived left the area for the best.
