Karymski volcano (Kamchatka): new ash explosion reported

Saturday Oct 06, 2012 12:05 PM | AUTEUR : T

VAAC Tokoy received a report about a possible eruption earlier today at 06:34 GMT and sent sent out a warning for an ash plume possibly up to 22,000 ft (7 km). The size of the eruption was estimated from the seismic record.
No ash was visible on satellite images and no further reports of a larger-than-average event were available, so most likely there was only a smaller explosion if at all whose ash quickly dissipated.

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.
