Volcanoes and air travel don’t mix well and the Bolshaya Volcano on the Kamchatka Peninsula in Eastern Russia has been stirring as of late, leaving officials concerned about a possible full-scale eruption.

From CNN.com:

“A volcano in the far eastern corner of Russia that was previously considered extinct may be waking up — and an eruption could be catastrophic. The Bolshaya Udina volcano — part of the Kamchatka Peninsula’s Udina volcanic complex — was believed to be extinct until 2017 when increasing seismic activity was detected beneath it, scientists say. Now, Ivan Koulakov, a geophysicist from Russia’s A.A. Trofimuk Institute of Petroleum Geology and Geophysics who led a study into the volcano, believes it should be reclassified as active. “At any moment, an eruption can occur,” Koulakov told CNN.”
