Russian volcano is still growing!
About 00:00 hours local time Wednesday /11:00 hours GMT Tuesday/, the Klyuchevskaya Sopka ejected a spout of ash to the altitude of 9,000 or so meters. The spouting could not be observed visually, as the crater of Eurasia's largest active volcano is coated in dense clouds, but data from satellites confirmed that a trail of the spout spread 80 kilometers westwards at the altitude of about 7,000 meters.
Also, the fallout of ash precipitation was registered in the town of Kozyrevsk located 45 kilometers away from Klyuchevskaya Sopka.
Surveyors have registered 124 seismic events near the volcano since Tuesday morning, including volcanic tremor of up to 83.9 mkm per second.
Researchers say Klyuchevskaya Sopka's activity rules out correct seismic monitoring of two neighboring volcanos -- Shiveluch and Bezymyanny.
As of February 15, the volcano, which is 4,750 meters tall, has been disgorging streams of lava about 1,000 degrees Celsius hot.
Fallout of ash is regularly reported from the towns of Klyuchi and Kozyrevsk, and people in the former town can occasionally hear walloping produced by the eruption.
Experts say Klyuchevskaya Sopka's activity does not pose any direct threat to population centers now but spokespeople for the Kamchatkan Volcanic Eruption Response Team /KVERT/ say ash trails may present a certain danger to aviation. The team has notified of it all the organizations and private companies concerned.
The volcano remains under permanent watch.
