Volcano news: Karymsky
Karymski volcano continues to have powerful strombolian to vulcanian type eruptions, producing ash plumes to 7 km (23,000 ft) a.s.l.
Explosive eruption continues at Karymski volcano. According to KVERT, on December 17, 2006, an ash plume rising up to 7.0 km (23,000 ft.) ASL and extending to the east from the volcano was observed by pilots.
Karymsky volcano is in increasing its activity, spewing ash clouds up to an altitude of 6,900 meters (22,637 feet) early on 4 Dec 2006....more
Karymski volcano remains the most active volcano on Kamchatka with frequent strong strombolian to vulcanian-type explosions producing ash plumes up to 3-4 km altitude....more
Karymsky volcano remains the most active volcano on Kamchatka, with strong strombolian to vulcanian activity, often producing ash-loaden plumes reaching 4-5 km altitude.
As KVERT reports, strombolian-to-vulcanian activity continued at Karymsky during the past weeks. Satellite imagery showed ash plumes extending ~40-145 km E and SE of the volcano, and a large thermal anomaly at the volcano's crater. Karymsky remained at Concern Color Code Orange.
Strong strombolian activity continues at Karymsky volcano with no significant changes. The volcano emitted frquently over the past week, and satellite imagery showed debris, most likely ash, draped along the sides of the mountain. When the skies were clear over the volcano, satellites also observed a thermal anomaly at the summit. In late March 2006, the USGS placed Karymsky at alert code orange, the second-highest level of concern. ->More on Karymsky

Strong strombolian activity at Karymsky volcano continues as KVERT reports. A large thermal anomaly over the crater, identifiable by satellite, persist and numerous ash plumes extending about 11-117 km (6.8-72.5 mi) to different directions from the volcano were observed over the past days.
The explosive activity at Karymsky volcano continues. Seismic data and satellite observations indicate ash explosions from the summit crater. Ash plumes might reach up to 6 km (or 19,700 ft.) a.s.l. A strong thermal anomaly over the volcanic crater was detected. Numerous ash plumes extend up to about 140 km (90 mi) to different directions from the volcano as observed on satellite images and present a hazard for low-flying aircraft in the area....more
As TASS reports, a swarm of about 300 local earthquakes were registered on Karymsky volcano on Thursday 9 Feb. 2006, and an ash plume of 1.5 km height is reported. There is no danger to nearby populated localities. The ash plume has stretched for about 20-40 east of the volcano.
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.
