The Kamchatka Peninsula is a 1,250-kilometre-long (780 mi) peninsula in the Russian Far East, with an area of about 270,000 km2 (100,000 sq mi), it is a host to around 160 volcanoes, 29 of them still active, and is included in the six UNESCO World Heritage.

The Pacific Ring of Fire

Kamachatka lies on the Pacific Ring of Fire, at a point where the Pacific Plate is sliding underneath the Eurasian Plate at a rate of about 80 mm/year. A wedge of mantle material lying between the subducting Pacific Plate and the overlying Eurasian Plate is the source of dynamic volcanism over the whole Kamchatka Peninsula.

Stratovolcanoes and Geysers are common at subduction zones, forming chains along plate tectonic boundaries where oceanic crust is drawn under continental crust. The most restless of these is Klyuchevskoy Group and Avachinskaya Group

Mt. Shiveluch, Kamachatka.

Shiveluch belongs to the Kliuchevskaya group, with an elevation of about 2,800 metres (9,186 ft). Shiveluch is one of Kamchatka’s largest and most active volcanic structures. It is a stratovolcano composed of alternating layers of solidified ash, hardened lava and volcanic rocks.

A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers of hardened lava, tephra, pumice, and volcanic ash.
Mt Klyucheskoi, Kamachatka.

Klyuchevskoi, is a stratovolcano of Klyuchevskoi Group, the highest mountain on the Kamchatka Peninsula of Russia and the highest active volcano of Eurasia. Its steep, symmetrical cone towers about 100 kilometres (60 mi) from the Bering Sea.

Mt Kronotsky, Kamchatka.

Kronotsky is a major stratovolcano to the east of Lake Kronotskoye on Kamchatka Peninsula, Russia. The summit crater is plugged by a volcanic neck, and the summit itself is ice-capped. It exhibits the classic radial drainage pattern, extending downward from its crater. Kronotsky is one of the most scenic volcanos in Kamchatka.

Mt Avachinsky, Kamachatka.

Avachinsky (also known as Avacha or Avacha Volcano or Avachinskaya Sopka)  is an active stratovolcano of Avachinsky Group on the Kamchatka Peninsula in the far east of Russia.

Mt Koryasky, Kamachatka.

Koryaksky or Koryakskaya Sopka is an active stratovolcano of Avachinsky Group on the Kamchatka Peninsula in the far east of Russia.

Mt Ksudach, Kamachtka.

Ksudach (also known as Vonyuchy Khrebet Volcano) is a stratovolcano of Avachinsky Group in southern Kamchatka, Russia. Two lakes, Balshoe and Kraternoe, are located within calderas at the summit of Ksudach.

Mt Ilyinsky, Kamachatka.

Ilyinsky or Ilyinskaya sopka is a stratovolcano of Avachinsky Group, located in the southern part of Kamchatka Peninsula, Russia near Kurile Lake.

Mt Kambalny, Kamachtaka.

Kambalny is a stratovolcano of Avachinsky Group located in the southern part of Kamchatka Peninsula, Russia. It is the southernmost active volcano of Kamchatka. It has erupted mafic rocks. It has a summit crater as well as five cinder cones on its flanks which are the source of lava flows.

Mt Karymsky, Kamachatka.

 is a symmetrical stratovolcano of Avachinsky Group, rising within a 5-km-wide caldera that formed during the early Holocene. Much of the cone is mantled by lava flows less than 200 years old. Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater. There is currently an ongoing non-stop eruption occurring, and is the peninsula’s most reliable volcano, which has been erupting continuously since 1996.

Zhemchuzhny geyser, Kamachatka.

The Valley of Geysers is a geyser field on Kamchatka Peninsula, Russia, and has the second largest concentration of geysers in the world. This 6 km (3.7 mi) long basin with approximately ninety geysers and many hot springs is situated on the Kamchatka Peninsula in the Russian Far East, predominantly on the left bank of the ever-deepening Geysernaya River, into which geothermal waters flow from a relatively young stratovolcano. Temperatures have been found to be 250 °C, 500 m below the caldera ground. It is part of the Kronotsky Nature Reserve, which, in turn, is incorporated into the World Heritage Site “Volcanoes of Kamchatka”.
