The Klyuchevskoi volcano in the tectonically active Kamchatka region in Russia’s Far East has been erupting sporadically since August.
"We have observed the latest ash eruption from the Klyuchevskoi volcano,” the local branch of the Emergency Services Ministry said in a statement. "The ash cloud is moving in a north-east direction.”
The highest mountain in the Kamchataka region, Klyuchevskoi has erupted in 2005, 2008, 2010 and 2012, spewing out lava and ash over the surrounding area.
The Emergency Services Ministry said in the statement that a red aviation warning was in place around Klyuchevskoi and cautioned tour companies not to take tourists near the volcano.
