Caldera

Karymshina caldera was discovered in 2006. The supervolcano is located southern region of Kamchatka Peninsula, about 50 km southwest of Petropavlovsk-Kamchatskii.

The caldera consists of a mountain massif containing several summits 1200–1300 m high. The highest peak is Mount Tolstyi Mys 1343 m. The caldera measures 25 km x 15 km.

From the caldera rivers flow both eastward to the Pacific Ocean (Paratunka and Lev. Bystraya rivers) and westward to the Sea of Okhotsk (Bannaya and Karymchina). North of the caldera is the Lake Nachikinskoe depression.

Geothermal activity
The volcano contains thermal springs: Bol’she-Bannaya, Mal. Bannaya, Karymchina, Karymshina, and Verkhne- Paratunka. A large magma chamber exists under the caldera which still contains heat.
