An active volcano on Russia's Kamchatka Peninsula on Tuesday spewed ash to a height of 6.5 kilometers (four miles), local emergencies services reported.
The 1,486-meter (4,875-foot) Karymsky is the most active volcano of Kamchatka's eastern volcanic zone. Its activity increased dramatically in 1996 and continues with periodic eruptions until the present.
"An ash eruption to a height of up to 6,500 meters took place at the Karymsky volcano early on Tuesday," the report said.
According to the report, the plume of ash is moving in the eastern direction from the volcano and poses no threat to nearby residential areas.
The emergencies ministry, however, issued a warning to local air traffic as the tiny ash particles often cause problems with aircraft engine turbines.
On Monday, another active Kamchatka volcano, the 3,283-meter Shiveluch, churned out ash to a height of up to five kilometers. No warnings were issued in the eruption.
There are more than 150 volcanoes on Kamchatka, 29 of them active.
