BackgroundA group of three small late-Quaternary Icelandic-type basaltic to basaltic-andesite shield volcanoes was constructed slightly east of the axis of the central Sredinny Range, about 30 km NE of Alney-Chashakondzha volcano. The three volcanoes are located to the north and NW of Lake Dvukhyurtochnoye. The highest and westernmost of the three volcanoes is 1349-m-high Zaozerny; 1081-m-high Oleny volcano rises above the north shore of Lake Dvukhyurtochnoye SE of Zaozerny, and 1164-m-high Kastriulya volcano was constructed NE of Zaozerny. Early geologic studies in the Sredinny Range (Ogorodov et al., 1972) identified numerous Holocene eruptive centers based primarily on morphological criteria. However, later work has suggested that Sredinny Range volcanoes are less mantled by Holocene tephras than eastern Kamchatka volcanoes and therefore appear more youthful, so that Holocene eruptions are uncertain for many of these Sredinny Range eruptive vents.
