What's going on in Zhupanovsky?
The Kamchatka Volcano Nature Park features two powerful plumes above the volcano and recommends travelers and tour operators to avoid the area. In the event of an eruption, gas concentrations could exceed the maximum allowed, and ash falls would be possible.
KVERT did not comment at this time on a possible volcanic activity.
