The Mount Hagi Ilias lava dome occupies the western side of a 3-4 km wide caldera at the summit of Nisyros volcano, the easternmost of the Aegean arc. Five large post-caldera lava domes completely fill the western part of the caldera. Historical phreatic eruptions occurred within the caldera between 1422 and 1888.
