KARYMSKY Eastern Kamchatka (Russia) 54.05°N, 159.45°E; summit elev. 1536 m [|KVERT] reported that seismic activity from Karymsky was above background on 11 and 13-15 April. Satellite imagery revealed a thermal anomaly from the volcano during 11-12 April. The [|Aviation Color Code] level remained at Orange. Geologic Summary. Karymsky, the most active volcano of Kamchatka's eastern volcanic zone, is a symmetrical [|stratovolcano] constructed within a 5-km-wide [|caldera] that formed about 7,600-7,700 radiocarbon years ago. Construction of the Karymsky stratovolcano began about 2,000 years later. The latest eruptive period began about 500 years ago, following a 2,300-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. Most seismicity preceding Karymsky eruptions has originated beneath Akademia Nauk caldera, which is located immediately S of Karymsky volcano and erupted simultaneously with Karymsky in 1996.

[|KVERT] reported that during 23-30 April seismic activity from Karymsky was above background levels, suggesting that possible [|ash] plumes rose to an altitude of 3 km (10,000 ft) [|a.s.l.] Volcanologists working in the area on 20 and 21 April saw gas-and-steam plumes containing some ash rise to an altitude of 3 km (10,000 ft) a.s.l. At night, [|Strombolian] activity was occasionally observed. Satellite imagery revealed a daily thermal anomaly over the volcano. The [|Aviation Color Code] level remained at Orange.
