Based on recent satellite detections of significant sulfur dioxide emissions and an increase in seismicity to a level above background, AVO raised the Aviation Color Code and Alert Level at Korovin Volcano to YELLOW/ADVISORY on October 28, 2020. Discrete earthquakes have been detected over the past two weeks and sulfur dioxide degassing has been detected four times in satellite data on October 15, 20 and 26. Clear satellite views show no other signs of activity at this time. AVO will continue to monitor the volcano for signs of volcanic activity.
In November, the unrest subsided, seismic activity returned to background levels and satellite observations showed no signs of further unrest. On December 3, 2020, AVO lowered the Aviation Color Code and Volcano Alert Level to GREEN/NORMAL.
