The Alaska Volcano Observatory (AVO) responded to eruptions, possible eruptions, volcanic unrest, and reports of unusual activity at or near eight separate volcanic centers in Alaska during 2009. The year was highlighted by the eruption of Redoubt Volcano, one of three active volcanoes on the western side of Cook Inlet and near south-central Alaska's population and commerce centers, which comprise about 62 percent of the State's population of 710,213 (2010 census). AVO staff also participated in hazard communication and monitoring of multiple eruptions at ten volcanoes in Russia as part of its collaborative role in the Kamchatka and Sakhalin Volcanic Eruption Response Teams.

The Alaska Volcano Observatory (AVO) responded to eruptions, possible eruptions, volcanic unrest or suspected unrest at 12 volcanic centers in Alaska during 2010. The most notable volcanic activity consisted of intermittent ash emissions from long-active Cleveland volcano in the Aleutian Islands. AVO staff also participated in hazard communication regarding eruptions or unrest at seven volcanoes in Russia as part of an ongoing collaborative role in the Kamchatka and Sakhalin Volcanic Eruption Response Teams.

The present paper, the first in the serives "The 300 Years of Kamchatka Volcanoes", examines the 350-year eruptive history of Young Shiveluch Volcano, which is the northernmost of the active volcanic edifices in Kamchatka; the history was reconstructed from historical documents and evidence, results of geological volcanological research and tephrochronologic dating using the 14C method. The results include the types, parameters, geologic-geomorphologic effect of the volcano's eruptions, environmental impact, estimated volume and weight of erupted and displaced material, the volcano's discharge rate. Since 1964 the dimensions of the new volcanic forms, the dynamics of their growth and decay, and the volume of ejecta were found using photogrammetric techniques. Part I. 1650-1964.

The first paper in the series “The 300 Years of Kamchatka Volcanoes” has examined the 350-year eruptive history of Young Shiveluch Volcano, which is the northernmost of the active volcanic edifices in Kamchatka: the history was reconstructed from historical documents and evidences, results of geological volcanological research and tephrochronologic dating as well as the 14C method. The results include the types, parameters, geologic-geomorphologic effect of the volcano’s eruptions, environmental impact, estimated volume and weight of erupted and redeposited material, the volcano’s discharge rate. Since 1964 the sizes of the new volcanic forms, the dynamics of their growth and destruction, and the volume of ejecta were calculated using photogram-metric techniques. Part II. 1965-2000.
