The dacitic lava flow at the right is part of the Dafni lavas, erupted early in the course of an eruption that lasted from 1925 to 1926. Like many other of Santorini's post-caldera eruptions, this eruption began with submarine explosions and lava extrusion. Explosive activity produced eruption plumes up to 3.2 km high. The east wall of Santorini caldera hosts the town of Firá across the caldera bay. Photo by Lee Siebert, 1994 (Smithsonian Institution).
