Greek officials have issued a warning about an increase in seismic activity on the popular Aegean island of Santorini.
They have advised residents to stay away from four ports, empty their swimming pools, avoid assembling indoors, and close schools on Monday.
According to a statement released by the civil protection ministry on Sunday, which cited experts responsible for monitoring Greece’s volcanic arc and evaluating earthquake hazards, more than 200 tremors have been recorded between the volcanic islands of Santorini and Amorgos since Friday.
School closures on February 3 have been extended to the islands of Amorgos, Ios, and Anafi as part of the precautionary measures suggested by the experts, who, according to the ministry, have determined that the tremors are not related to volcanic activity.

People in Santorini have been advised to avoid the harbour of Fira, which is mostly used by cruise ships, as well as the tiny ports of Ammoudi, Armeni, and Korfos. Soaring granite faces encircle many of Santorini’s ports.
Santorini officials were getting ready for a possible evacuation when Prime Minister Kyriakos Mitsotakis led an emergency meeting on the matter in Athens.
Police and fire personnel were on high alert, special disaster response units were on standby, and tents were erected in an outdoor stadium.
Greece frequently experiences earthquakes since it is situated on several fault lines.
Professor of geophysics and seismology Costas Papazachos, who visited Santorini to evaluate the situation, stated that the precautions were necessary and that an earthquake with a magnitude of 6.0 or higher would be the worst-case scenario.
“This does not necessarily imply that a powerful earthquake will occur; it is possible that the heat energy will dissipate and that Santorini will experience a milder earthquake instead. However, we must take action,” he said to the Greek website protothema.gr.
Approximately 3 million tourists visit Santorini each year, which is known for its black sand beaches and whitewashed homes that cling to its sheer cliffs.
Around 1600 BC, the island’s current shape was created by one of the biggest volcanic eruptions in history. The region’s most recent eruption took place in 1950.
