Klyuchevskoy, the highest volcano in Russia, erupted on March 2 this year. As reported by the Kamchatka Volcanic Eruption Response Team (KVERT) on the same day, Klyuchevskoy had been spewing ash and steam 20,000 feet in the air. The KVERT also mentioned that several emissions of ash approximately 16,400 to 23,000 feet may take place at an indefinite date and time. The said eruption was classified as orange based on the aviation color code, which indicates that the volcanic ash formed from the eruption has a potential hazard that may affect flights. According to the United States Geological Survey (USGS), the ash particles can damage the navigation equipment of aircraft once they are absorbed and re-solidified inside the engines.

Klyuchevskoy is a stratovolcano located in the Kamchatka Peninsula of East Russia. It is the most active volcano in Eurasia with a height of 15,580 feet, and is speculated to have an estimated age of 7,000 years. The volcano is part of the Klyuchevskaya group, where 160 more volcanoes can be found. 26 out of the mentioned number of volcanoes are noted to be active, and researchers discovered seismic activity surrounding one of the restless volcanoes last 2019.
