During the Post-Caldera eruptive cycle, the last magmatic activity that took place in Nisyros up to 15000 years ago, huge amounts of lavas of rhyodacitic composition were emitted following the second collapse that formed the present-day caldera.
The highly viscous lavas created a series of endogenous domes that gradually grew and partially filled the western part of the caldera and the southwestern coast of the island, without any signs of explosive activity. One such dome is Karaviotis, with a maximum height of 539m, that is generally younger than the intra-caldera ones and its lavas flow towards the southwest and into the sea. It provides unique views toward the youngest magmatic products of Nisyros.
