BackgroundIettunup and Lamutsky are small overlapping late-Quatenary Icelandic-type basaltic to basaltic-andesite shield volcanoes that were constructed east of the Sredinny Range crest, forming the NE-most Quaternary volcanoes of the Sredinny Range. The 1340-m-high Iettunup is located NW of the 1198-m-high Lamutsky 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.
