The Greek Ministry of Shipping and Insular Policy has prohibited cruise ships from approaching Santorini due to the continuing seismic activity, raising concerns over passenger safety and the island’s infrastructure. 

“Scientists are now talking about an unprecedented phenomenon, with fluctuations in its dynamics, which does not yet allow a safe assessment of its evolution,” said Prime Minister Kyriakos Mitsotakis.

The decision, announced due to increased tremors in the region, was backed by industry experts. Theodoros Kontes, president of the Association of Cruise Ship Owners and Shipping Operators, said that Santorini is currently not a safe destination for large cruise ships carrying thousands of passengers.

"The move by the Ministry is justified," Kontes said. "Insurance companies have "squeezed" shipowners quite a bit for a possible damage that will occur on the island. Due to the huge number of passengers and crew, insurance companies lose a lot of money if a damage occurs."

Some ships have already diverted to alternative Greek ports, such as Souda, Heraklion, and Syros."
The ban has sparked concerns among local businesses. Antonis Linos, president of Thira’s catering sector, acknowledged the disruption but remained hopeful:
“The emergency measures are in effect until March 3. Residents and workers are beginning to return. It’s only a matter of time before normality is restored.”

Greek Prime Minister Kyriakos Mitsotakis addressed the situation over the weekend, warning that seismic fluctuations remain unpredictable.

"Scientists are talking about an unprecedented phenomenon with dynamic changes that do not yet allow a safe assessment of its evolution," Mitsotakis said. "The state mechanism remains on alert, following expert recommendations."
