Santorini has experienced over 200 earthquakes within a week, leading to school closures on multiple Greek islands and increased ferry and flight services for residents and tourists leaving. While the earthquakes, with magnitudes up to 5.1, have prompted emergency measures and warnings about potential larger quakes, experts confirm they are tectonic and unrelated to volcanic activity. Notably, some tourists are enjoying the quieter island, despite the tremors. Greek Prime Minister Kyriakos Mitsotakis has called for calm as officials continue to monitor the seismic situation, which remains unpredictable.
