Tremors Shake Santorini: Island Takes Precautionary Measures

Greek authorities urge caution as Santorini experiences increased seismic activity, prompting school closures and advice against large gatherings.


With recent tremors recorded at magnitudes reaching 4.6, Santorini's safety protocols are in full effect as the island prepares for any further seismic events.

Authorities on the picturesque Greek island of Santorini are on high alert in response to a series of tremors that have rattled the region in recent days. Effective Monday, schools across the island have been directed to close amid increasing seismic activity, which has included quakes measuring up to 4.6 in magnitude. The local government has also recommended that residents and visitors refrain from large gatherings in enclosed spaces, particularly in light of the island's status as a popular tourist destination, famous for its stunning architecture and breathtaking views.

Over the weekend, additional tremors of 4.3 and 3.9 magnitudes were recorded in the surrounding area. Santorini lies on the Hellenic Volcanic Arc, characterized by its volcanic landscape formed through tectonic plate movements. However, experts have noted that these recent earthquakes are linked to tectonic shifts rather than volcanic eruptions, and activity in the region’s volcanic caldera appears to be declining.

Despite the tremors being deemed minor or light, precautionary actions are being taken, including warnings for ships to steer clear of the ports of Ammoudi and Fira, where large cruise liners typically dock. Authorities are urging caution against visiting abandoned structures and avoiding travel through areas prone to landslides.

Kostas Papazachos, a geophysics professor at Aristotle University in Thessaloniki, emphasized the importance of these safety measures to mitigate the effects of future seismic events. "A sequence of tremors can create panic among people in large groups, leading to potential injuries," Papazachos stated on public broadcaster ERT.

As Santorini's small population of around 15,500 swells each summer with millions of tourists, the South Aegean Regional Fire Department has been placed on general alert with rescue teams strategically deployed to the island. The UK Foreign Office also updated its travel advice to British citizens, emphasizing ongoing safety measures.

Historically, Santorini has a remarkable volcanic past, with one of the largest eruptions around 1600 BC shaping the island into its current crescent-like form. While human settlement dates back to the Bronze Age, the island's most catastrophic eruption occurred in 1956, resulting in the loss of over 50 lives. As authorities closely monitor the seismic activity, residents and visitors are reminded to stay vigilant.
