The monograph is devoted to the spatio-temporal activation of Holocene volcanism within the Miocene-Quaternary volcanic zone of the Sredinny Range of Kamchatka. The pattern of volcanic activation, grouping elements and periodic pulses of endogenous activity, as well as their chronological relationship with episodes of endogenous activity increasing of the North Pacific. The characteristics of individual volcanic centers and the largest eruptions are provided. Age determinations of eruptions are based on detailed tephrochronological research and extensive radiocarbon dating.
For a wide range of professionals in the field of geology, geochronology, volcanology, petrology, geography,
geomorphology, paleoclimatology, ecology and geobotany.

Numerous Holocene volcanic centres (5 stratovolcanoes, including 4 active and potentially dangerous, and 12 monogenetic centres) are discovered within Sredinny Range of Kamchatka. Their exact ages are determined. Spatial and temporal characteristics, as well as composition of Holocene volcanic rocks witness against direct connection of magma genesis with contemporary Pacific plate subduction. Sub-meridional chronological trends and elements of grouping, identified for Holocene volcanic activity of Sredinny Range of Kamchatka, may indicate seismo-geodynamical nature of young volcanic activity and associated with it advection in the extinct island arc system.

Mount Rannyaya (86°58' S, 163°20' W, 2270 m a.s.l., 18-20 Ма) и Sheridan Bluff (87°04' S, 153°46' W, 2720 m a.s.l., ~ 16 Ма) were explored in 1934 and 1962-1963, and studied and dated in 1978-1979 bу Antarctic researches. The article shows that these volcanoes are typical tuya, the oldest and high-latitude volcanoes on Earth. It confirms that in early Miocene thick glaciers existed in western Antarctic near the Pole, and subglacial volcanic activity was strong.
