The Planet's Violent Epicenter -A Sweeping Arc of 160 Volcanoes

Volcano_3The 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.

Karm2The 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.

There are quite few active volcanos in the northern emisphere.
Some are also in the US.

I DO NOT know if this is the most active...BUT I have serious doubts.

It may very well be the highest .

Regards from Italy a place where active volcanos DO exist.

If you read what he said, it is the LARGEST active volcano. Not the most active volcano

I am not much into reading, but somehow I got to read lots of articles on your blog.
Its amazing how interesting it is for me to visit you very often :)

Awesome! I have read a lot on this topic, but you definitely give it a good vibe. This is a great post. Will be back to read more! Please come visit my site Plano Yellow Page Business Directory when you got time

By the way - when anyone is projecting the effects of climate change and the increasing temperatures due to ..whatever, let it not me forgotten what the eruption of Mt Pinatubo did in the 80's. It lowered the earths temperature by 2 degrees for YEARS. One good platonic shift, and a few of this smokers fire off (as they Will!) and we will be headed for a nuclear winter without the atomic bombs or methane escaping from the ocean floor. DUH....
