Background
The volcanoes and associated lava flows cover a 65-km-long, 35-km-wide area west of Lake Sevan and south of the Hrazdan River and are concentrated along 3 NNW-SSE-trending alignments. Lava flows from the central and eastern clusters flowed into Lake Sevan. Initial explosive eruptions at the Ghegam Ridge volcanic field were followed by the extrusion of rhyolitic obsidian lava domes and flows. The latest activity produced a series of andesitic and basaltic-andesite cinder cones and lava flows. The central and eastern portions of the Ghegam Ridge contains large areas of Holocene eruptions with morphologically fresh lava flows devoid of vegetation.Ghegam Volcano Photos
