About this site
Aspronisi is a small islet within the Santorini caldera, lying between Therasia and the main island of Thera, part of the volcanic rim formed by the Bronze Age eruption. The seabed around Aspronisi is shaped by volcanic rock formations rather than coral reef, reflecting the area's geological origins. Divers have also reported dusky spinefoot, Indian lionfish, Mediterranean damselfish, and Mediterranean fanworm along this stretch.
