Background:Anaun is a late-Quaternary basaltic stratovolcano located NE of Uksichan volcano in the southern Sredinny Range. A chain of NE-SW-trending youthful cinder cones extends to the SW from 1828-m-high Anaun, and another chain with numerous cinder cones displays the same orientation south and SE of the volcano. 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.
