Yavinsky is an early to mid-Pleistocene basaltic volcano that forms an arcuate ridge (Yavinsky Khrebet) along the SW coast of Kamchatka, overlooking the town of Ozernovsky and the mouth of the Ozernaya River. A Holocene basaltic cinder cone named Ukho (which means "Ear" in Russian), related to regional basaltic monogenetic volcanism, was constructed on the NW flank about 6,000 years ago, based on stratigraphic evidence. However, Yavinsky itself was not included by Ponomareva et al. (2007) in their review of Holocene volcanoes in Kamchatka.
