In brief
Recent minor earthquakes prompt school closures and warnings for residents and travelers alike.
Santorini, a stunning Greek island famous for its picturesque landscapes, is currently under alert due to heightened seismic activity recorded in the region. Schools are set to close on Monday, and local authorities have advised against large gatherings in confined areas as tremors of up to 4.6 magnitude rattled the island, with additional minor quakes of 4.3 and 3.9 occurring nearby on Sunday.Santorini, located on the Hellenic Volcanic Arc—a series of volcanic islands formed by tectonic plate interactions—has not experienced a significant eruption since the 1950s. Recent earthquakes have been attributed to tectonic movements rather than volcanic activity, and experts assert that volcanic activity in the caldera surrounding the island is currently on the decline.Despite the tremors being classified as minor or light, authorities are urging residents and tourists to take precautions, including the temporary closure of schools on the nearby islands of Anafi, Ios, and Amorgos, and a recommendation for vessels to avoid the ports of Ammoudi and Fira, which are frequented by large cruise ships. Additionally, residents are advised to steer clear of abandoned structures and risky travel routes prone to landslides.Kostas Papazachos, a geophysics professor at Aristotle University, articulated the need for caution amid these seismic events, stressing the importance of preparedness against potential stronger earthquakes. He highlighted the danger posed by crowded areas during tremors, which could incite panic and lead to injuries.To ensure the safety of the population, which swells with millions of tourists annually, the South Aegean Regional Fire Department has been placed on high alert, with rescue teams mobilized to the area. The UK Foreign Office has also updated travel advice for its citizens visiting Santorini.Historically, the island, still bearing evidence of human settlement dating back to the Bronze Age, witnessed one of the most significant volcanic eruptions around 1600 BC, forming its iconic crescent shape. The most catastrophic eruption prior to the current alert occurred in 1956 and resulted in over 50 fatalities.
