In an alert notice issued on Nov. 27, the alert level for Tolbachik volcano, located on the Kamchatka Peninsula in Russia, was raised
from Green to Yellow. Now the level has been raised again as the volcano becomes more active.
As of Nov. 28, the alert level for the 3,085-meter (10,121 feet) volcano is now designated to Orange, according to KVERT
(Kamchatka Volcanic Eruption Response Team).
Orange is the third of four tiers of volcanic activity, with Red being the most severe. With an orange designation, KVERT notes the volcano is "exhibiting heightened unrest with increased likelihood of eruption," or
"Volcanic eruption is underway with no or minor ash emission."
“Explosive eruption of the volcano began on November 27. Ash explosions up to 32,800 ft (10 km) a.s.l. could occur at any time. Ongoing activity could affect international and low-flying aircraft,” KVERT said on its website.
Tremors from the slumbering volcano reportedly began on Nov. 7 and the activity has steadily been increasing. RIA News
reported experts are saying Tolbachik "poses limited hazards."
Reportedly, some villages are saying they've experienced ash falls and lava flows. At this time, the region is being monitored for any impact on air travel over the eastern side of Siberia, according to Wired News
According to RIA, Tolbachik has only erupted 10 times since 1740; its last eruption occurred in 1975-76.
