One of the most active volcanoes on the Kamchatka peninsula, "Shiveluch" (or Sheveluch), South Eastern Russia has been erupting recently. The volcano has had over 60 large explosions in the last 10,000 years with the most recent catastrophic eruption being in 1956. The volcano itself is 65,000 years old and is about 2,800 metres high.

The volcano is monitored by KVERT who have reported a viscous lava flow on the volcanoes North flank from 12-19 of July this year.

Klyuchevskaya Sopka, the highest of all the Kamchatka volcanoes at 4,750m above sea level, has also been active recently. On the 25th January 2013 a strombolian eruption was recorded, featuring the expulsion of some incandescent cinders and low-energy ejection of lava bombs.

Shiveluch lies on the Pacific ring of fire, an area surrounding the Pacific ocean with a large amount of tectonic activity, and is a UNESCO world heritage site. Shiveluch was formed as a result of a destructive plate margin between the Pacific and North American plates and is characterised as a stratovolcano otherwise know as a composite volcano.

The Aleutian ocean trench to the west of Kamchatka is the ocean trench from this plate margin, and can be seen clearly on the location image (three above).

Composite volcanoes are common at subduction zones and are particularly explosive. There is however little danger to the nearest settlement Klyuchi which is 50km away and is so small it could evacuate quickly in the case of a large eruption.
Above is a video of some recent activity during January this year. In fact the current eruptions are classified as being part of the same continuous eruption that started in 1999.
To finish, a slightly related song about the ring of fire (however not the Pacific one) from Johnny Cash.
