On 12 June ash plumes from Klyuchevskoy rose to an altitude of 5 km (16,400 ft) a.s.l.
and drifted 10 km N, prompting KVERT to raise the Aviation Color Code to Orange (the second highest level on a four-color scale).
Ash emissions continued later that day with plumes rising to 5 km a.s.l.
and drifting 68 km WNW.
