Abstract
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 km2. 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 km3, of which 0.004 km3 consisted of ash and 0.006–0.01 km3 were pyroclastic flow deposits.
