The ancient island of Delos, one of Greece’s most important archaeological sites and a UNESCO World Heritage location, is increasingly vulnerable to rising sea levels and gradual land subsidence, according to new research presented at the Academy of Athens.
A study conducted by scientists from the Academy of Athens, the National Observatory of Athens and the Ephorate of Antiquities of the Cyclades found that the island is sinking by almost one centimetre each year. The findings are based on data collected from a climate monitoring station installed on Delos two years ago, combined with historical records, archaeological evidence and tide-gauge measurements.
According to ekathimerini.com, researchers say the phenomenon is being driven by a combination of sea-level rise across the Aegean and the island’s geological characteristics, which make it particularly susceptible to land subsidence.
Natural disaster specialist Kostas Synolakis warned that future increases in relative sea level are largely unavoidable due to the long-term effects of ocean warming. Current projections suggest sea levels around Delos could rise by between 21 and 28 centimetres by 2050, and between 48 and 87 centimetres by the end of the century.
The changes are expected to have significant consequences for the island, including coastal erosion, the expansion of wetland areas and the complete submersion of parts of its ancient harbour infrastructure that are already partially underwater.
Researchers also warned that key visitor areas could face increased flooding, raising concerns about the long-term preservation of one of the Mediterranean’s most important cultural and historical landmarks.
