The Kamchatka River and the surrounding central side valley are flanked by large volcanic belts containing around 160 volcanoes, 29 of them still active.
A volcanic belt is a large volcanically active place.
The youngest volcano within the volcanic belt is Nazko Cone.
It has over 150 volcanic belts (now deformed and eroded down to nearly flat plains) whose bedrock ranges from 600 to 1200 million years old.
They are grouped into five volcanic belts with different volcano types and tectonic settings.
Many of the volcanic belts bear ore deposits that are related to the volcanism.
The lavas of the volcanic belt display geochemical characteristics similar to modern ocean-island-basalt groups.
The volcanoes are grouped into four volcanic belts with different tectonic settings.
It contains over 150 volcanic belts (now deformed and eroded down to nearly flat plains) that range from 600 to 1200 million years old.
However, at the time of its formation the volcanic belt may have been coincident with the subducted plate boundary.
