An explosive eruption occurred on Bezymyannyi Volcano December 24, 2006. The distribution of ashfall deposits over the peninsula was studied. The tephra was investigated for its chemical, mineral, and grain-size composition, its water-soluble complex was studied. About 30 000 tons of water-soluble substances along with 7 million tons of ash entered the environment over an area of over 8000 km^sup 2^. Information is supplied for this eruption from various sources and its geological impact has been estimated. The total volume of erupted pyroclastics was 0.01-0.014 km^sup 3^, of which 0.004 km^sup 3^ consisted of ash and 0.006-0.01 km^sup 3^ were pyroclastic flow deposits.[PUBLICATION ABSTRACT] Show less
