Karymsky volcano (Eastern Kamchatka, Russia) - Smithsonian / USGS Weekly Volcanic Activity Report for 19 July-25 July 2017 (Continuing Activity)

KVERT reported that explosions at Karymsky on 18 July generated ash plumes that rose 1.7 km (5,600 ft) a.s.l. Satellite images showed a weak thermal anomaly over the volcano during 18-20 July, and ash plumes drifting 117 km E on 20 July. The Aviation Color Code remained at Orange (the second highest level on a four-color scale). ... Read all

Background:

Karymsky, the most active volcano of  Kamchatka's eastern volcanic zone, is a symmetrical stratovolcano constructed within a 5-km-wide caldera that formed during the early Holocene.  The caldera cuts the south side of the Pleistocene Dvor volcano and is located outside the north margin of the large mid-Pleistocene Polovinka caldera, which contains the smaller Akademia Nauk and Odnoboky calderas. 
Most seismicity preceding Karymsky eruptions originated beneath Akademia Nauk caldera, which is located immediately south of Karymsky volcano.  The caldera enclosing Karymsky volcano formed about 7600-7700 radiocarbon years ago; construction of the Karymsky stratovolcano began about 2000 years later.  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.  Historical eruptions have been vulcanian or vulcanian-strombolian with moderate explosive activity and occasional lava flows from the summit crater.
