BackgroundPogranychny is the highest and easternmost of a group of three small late-Quaternary Icelandic-type basaltic to basaltic-andesite shield volcanoes located NE of Cherny volcano in the central Sredinny Range. Centralny volcano is at the SW end of the group, and Vodorazdelny is at the north. A NNE-SSW-trending chain of cinder cones extends across Vodorazdelny to Centralny. 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.
