Earth’s Volcanic Epicenter – A Sweeping Arc of 160 Volcanoes

6a00d8341bf7f753ef00e5505dfbef8834.jpg The Kamchatka Peninsula is a 1,250-kilometer long peninsula in the Russian Far East. The Kamchatka River and the surrounding Central Valley are flanked by large volcanic belts, containing around 160 volcanoes, 29 of them still active. The peninsula has the highest density of volcanoes and associated volcanic phenomena in the world, with 19 active volcanoes being included on the UNESCO World Heritage List.

The highest volcano is Klyuchevskaya Sopka (4,750 m or 15,584 ft), the largest active volcano in the Northern Hemisphere], while the most striking is Kronotsky, whose perfect cone is a prime candidate for the world's most beautiful volcano.  Deep seismic events and tsunamis are fairly common along the Kuril-Kamchatka Trench: a pair of megathrust earthquakes occurred off the coast on October 16, 1737, and on November 4, 1952, in the magnitude of ~9.3 and 8.2.

The Karymsky volcano is a symmetrical stratovolcano constructed within a 5-km-wide caldera that formed during the early Holocene.

The latest eruptive period began about 500 years ago, following a 2300-year quiescence. Much of the cone is mantled by lava flows less than 200 years old.
