One of the most important structural factors in the formation of volcanoes and molten materials is their formation. Volcanic eruptions cause deformation of morphology and the creation of a new landform. Damavand volcano has made significant changes around its quaternary as a complication with its successive eruptions. In this research, the role of Damavand lava in the creation of dam lakes has been investigated. To achieve this goal, the analytical method and the timing of the change have been applied.The technique of comparing the morphometry of lagoons and lava dams is based on three ways of comparing the height and thickness of alluvial deposits, determining the extent of spreading of sediments of the lakes, and the restoration of the last elevation of lavaes overlooking the valleys. Lake Haraz, at 2550 meters and with an area of ââ54/44 square kilometers, lar lake is located at a height of 2580 meters with an area of ââ68/79 and Dilichai lake at an altitude of 3780 meters above sea level, with an area of ââ25 square kilometers. These three lakes are formed almost simultaneously. The lava streams of these three lakes are separated and consecutively put together. The lakes are connected through the swells, which led to the formation of the current duct.
