A group of six cinder and lava cones of Pleistocene-to-Holocene age is located in southern Armenia on the western slopes of the Vardeniss volcanic ridge, south of Lake Sevan.
The andesitic Dar-Alages volcano, also known as Daly-Tapa, formed in postglacial times (Sviatlovsky, 1959). The Vaiyots-Sar and Smbatassar pyroclastic cones of Holocene age (Karakhanian et al., 2002) are located in this part of the Vardeniss volcanic ridge. Vaiyots-Sar volcano lies just north of the major Areni-Zanghezour Fault, near the town of Vaik, and produced a fissure-fed lava flow several thousand years ago that dammed the Arpah River and flowed to the west for 6 km. The youthful-looking Smbatassar cinder cone is located 17 km to the NW and produced lava flows that traveled 11 and 17 km north and south, respectively.
