Aag Volcano is part of Avachinsky-Koriaksky volcano group made up of 5 volcanoes in the eastern range. It is located in Nalychevo Nature Park included in the UNESCO World Cultural and Natural Heritage List.
With volcanoes Koriaksky and Avachinsky they form the “Three volcanoes” zoological Reserve.
This complex extinct volcano reaches a height of 2,310 meters. It is attached to Arik volcano (2,156m). The two of them are strongly eroded by glaciers. The south western side is made of steep cliffs and 200 to 400 meters deep ravines. Another ravine is located on the north eastern side of Aag volcano and is quite dangerous because of fallen rocks coming from the summit. On this same side extrusive domes were created as well as cinders and lava cones.
The date of volcano Aag’s last eruption is unknown. At the north west of the volcano’s bas, up Chumnaya River are located several hot springs. The volcano attracts many excursions and extreme sports enthusiasts.
