Kamchatkan Kliuchevskoi volcano continues to violently erupt with lava fountains from the summit and lava flows on the flank. Last evening, ash emissions again reached almost 8 - 9 km (30 000 ft) altitude. Current Aviation Color Code is RED - Eruption is underway with significant emission of ash into the atmosphere.
KVERT monitors the situation closely and issues alerts every few hours.
Explosive activity of Kliuchevskoi volcano at 03:56 UTC on October 19, 2013.

In their latest notice, issued 03:50 UTC today, KVERT reports:
"Ash plume height decreased to 6.5 - 7 km (21 300 - 24 600 ft) a.s.l. but plume containing a big amount of ash extended about 1188 (736 miles) to the south-east and east of the volcano (satellite data at 01:35 UTC on October 19, 2013).
Explosive-effusive eruption of the volcano continues.
Ash explosions up to 10 km (32,800 ft) a.s.l. are possible. Ongoing activity could affect international and low-flying aircraft." - VONA/KVERT Information Release, October 19, 2013. KVERT, Institute of Volcanology and Seismology FEB RAS.

Meanwhile, nearby Shiveluch has increased its activity too. Strong ash emissions of the volcano uninterruptedly continues and extend on the height about 3 - 3.5 km a.s.l. to the south of the volcano. Fresh lava is extruding at the lava dome uninterruptedly - a big and bright thermal anomaly is noting at the volcano by video data and satellite images. Aviation Color Code of Shiveluch is ORANGE.
