Kambalny, which has a height of 2,156 meters above sea level, began spewing ash on Friday evening. The ash rose to a height of 7,000 meters above sea level and traveled a distance of 255km in a south-westerly direction.
The Kamchatka Volcanic Eruption Response Team (KVERT) of the Russian Academy of Sciences' Institute of Volcanology and Seismology has notified air traffic controllers of the danger of a volcanic eruption.
The volcano has been assigned an orange aviation color code, which means that the volcano is exhibiting heightened unrest with increased likelihood of eruption.
Residents in the village of Ozernovskiy, the nearest settlement located 77 km away from the volcano, have been informed of the threat.
