Type
Pyroclastic cone
Elevation

Last eruption
-2000
The Vaiyots-Sar scoria cone has a roughly 500-m-wide summit crater, seen in this August 2020 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 15 km across). Lavas with visible flow boundaries and levees are to the NW and S to SW of the cone, with some long, linear flows and some much broader flow fronts with pressure ridges.

Geological summary

The Vaiyots-Sar pyroclastic cone is located in the southern Armenia province of Vayots Dzor in the western Vardenis Volcanic Highland south of Lake Sevan (Karakhanian et al., 2002); previous names such as Dar-Alages or Daly-Tapa are of Russian origin.

From Wikipedia

Dar-Alages is a group of six cinder lava cones south of Lake Sevan in Armenia. Fissure eruptions from Vaiyots-Sar dammed the Arpa river at Vayk and continued down the valley for 6 km. These lava flows are considered Holocene in age given the lack of a soil cover and their placement above a Pleistocene river terrace. Smbatassar cinder cones likewise generated two lava flows of 11 and 17 km length that overlie Pleistocene Yeheghis river terraces, thus also dating to the Holocene. Legends of the destruction of the towns Yegheghis and Moz in 735 AD may be linked to activity in these volcanoes.
