BeschreibungUka, a small late-Quaternary Icelandic-type basaltic shield volcano, was constructed near the eastern margin of a large NE-SW-trending graben running along the axis of the northern Sredinny Range. The 1643-m-high Uka volcano is located immediately east of the crest of the Sredinny Range, opposite Alngey volcano, located on the western side of the graben. 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.
