The most serious situation persists at the Shiveluch volcano, which currently has an orange aviation color code. This means that volcanic activity could pose a hazard to aircraft.

According to KVERT, the explosive-effusive eruption of Shiveluch continues. Ash emissions up to 12 kilometers above sea level are possible at any time. Aerosol and ash clouds may pose a danger to flights on international and local airlines.

Over the past week, Shiveluch has exhibited intense steam-and-gas activity, along with the growth of a new lava block in the northern part of the lava dome. On June 12, ash rose to 6 kilometers, and on June 17 — to 10 kilometers above sea level.

Satellite data show that a thermal anomaly was observed at the volcano every day of the week. On June 17–18, the ash cloud drifted 925 kilometers northeast of the volcano.

A yellow aviation code is in effect for the Bezymianny and Krasheninnikov volcanoes.

At Bezymianny, an effusive eruption continues. Aerosol clouds may pose a threat to local airlines. A thermal anomaly was also recorded at this volcano throughout the week.

At Krasheninnikov, an eruption continues with lava flows descending along its eastern slopes. The process is accompanied by steam-and-gas activity. The risk of ash emissions reaching up to 6 kilometers above sea level remains.
