The highest volcano in Russia, Klyuchevskoy, erupted last March 2 this year according to a report by the Kamchatka Volcanic Response Team (KVERT). The report included that the volcano had been emitting ash and steam 20,000 feet in the air, and possible volcanic ash discharge of around 16,400 to 23,000 feet may occur. The aviation color code categorized the eruption as orange, which identifies the volcanic ash from the eruption as unsafe to aircraft. The United States Geological Survey (USGS) has noted that the ash particles can potentially impair the engines and navigation apparatus of airplanes.

Klyuchevskoy is located in the Kamchatka Peninsula of East Russia, and is considered as the most active volcano in Eurasia, the continent which refers to Europe and Asia as one. The volcano is believed to be around 7,000 years old, with a height of 15,580 feet. It is part of the Klyuchevskaya group where 160 more volcanoes are found, 26 of which are reported to be active.
