The iconic Greek island of Santorini has experienced a significant seismic event, with over 200 earthquakes detected between Friday and Sunday. In response to this alarming activity, local authorities have announced the closure of schools on Monday, ensuring the safety of students and staff. The tremors, which included a notable quake measuring 4.6 in magnitude, have prompted school closures not only in Santorini but also in the nearby Aegean islands of Anafi, Ios, and Amorgos.
Authorities have advised residents to avoid large indoor gatherings and to steer clear of multiple ports, particularly the old port of Fira, as a precautionary measure. An emergency committee convened on Sunday to assess the risks associated with the recent seismic activity, with another meeting scheduled for Monday to reevaluate the situation.
Despite the increased seismic activity, Santorini remains a popular tourist destination, attracting approximately 3.4 million visitors each year. The island is home to around 20,000 residents and is famed for its breathtaking views and photogenic landscapes, which have earned it the nickname "Instagram island." Tourists flock to Santorini for its stunning sunsets and scenic vistas, all set against the backdrop of its crescent-shaped caldera—a geological feature formed by one of the largest volcanic eruptions known to have occurred around 3,600 years ago.
Santorini's geological history is rich and complex. The island sits on several fault lines, making it prone to earthquakes. The last significant earthquake recorded in Santorini was a devastating 7.5 magnitude quake on July 9, 1956, which generated a tsunami that reached heights of approximately 25 meters (around 80 feet). Previous increased seismic activity in 2011 and 2012 did not result in any volcanic eruptions, offering some reassurance as residents and officials monitor the current situation.
The Hellenic Volcanic Arc, where Santorini is located, is recognized as one of the most active volcanic fields in Europe, with over 100 eruptions documented over the past 400,000 years. Given this context, the recent spate of earthquakes serves as a reminder of the island's dynamic geological character.
