SANTORINI, Greece (AP) — Emergency crews deployed on the volcanic Greek island of Santorini on Monday after heightened seismic activity caused concern about potentially powerful earthquakes. Schools were closed and safety measures put in place across Santorini and nearby Aegean islands — popular summer vacation destinations — following the record of more than 200 undersea earthquakes over just three days.
These recent seismic events, which included quakes measuring up to 4.8 magnitude, prompted Civil Protection Minister Vasilis Kikilias to hold emergency meetings with government officials and scientists. Kikilias stated, “These measures are precautionary, and authorities will remain vigilant.”
While experts assert the increased tremors are linked to tectonic activity rather than volcanic movements from Santorini's famous caldera, the situation remains cause for concern. Seismologist Gerasimos Papadopoulos noted the clustering of tremors on seismic maps, indicating the possibility of more significant seismic events to come. “All scenarios remain open,” he mentioned, referencing the intensifying quake patterns.
Several nearby islands, including Amorgos, Anafi, and Ios, also saw school closures and public advisories to avoid gatherings indoors and be cautious of areas prone to rockslides. The preemptive measures included draining swimming pools to minimize potential earthquake damage. The island’s Fire Service rescuers set up tents for emergency assistance outside the local hospital.
Residents, anxious about the persistent shaking, reacted by either leaving the island or spending the night camped in cars. The most powerful tremors struck throughout the weekend, with many registering over 4.0 on the Richter scale. The strongest earthquake recorded reached 4.7 on Sunday evening.
Kostas Papazachos, a geophysics professor at Thessaloniki’s Aristotle University, emphasized the urgency of the situation, stating, “Nothing can be ruled out.” He and local officials expressed concern about the potential for larger movements or even volcanic activity. The tremors could lead to unpredictable consequences, and safety protocols were put on high alert.
The island, known for its stunning views and vibrant tourism, usually attracts over three million visitors annually. Many travelers were advised to steer clear of the coast due to tsunami fears, and ferry services were altered amid the anxiety surrounding the seismic swarm.
Prime Minister Kyriakos Mitsotakis participated in discussions about the increasing seismic activity, confirming continuous updates would be provided as information became clearer. “The measures taken so far are precautionary. I urge everyone to rely on accurate and verified information,” Kikilias reiterated during these deliberations.
Meanwhile, reports came from ferry companies indicating foreign workers were leaving for the port of Piraeus following warnings. Tours of popular sites were suspended, with travel advisories from the U.S. and U.K. cautioning against exposure to potential hazards. With the situation still developing, residents remained on edge as tremors continued to rock the island.
Specific attention was directed toward areas prone to landslides, identified as high-risk zones by disaster management experts. The locations included Athinios, Old Port, and several others where vulnerable rock formations posed significant threats. Efthymios Lekkas, President of the Organization for the Management of Earthquake Victims, noted the seismic activity is unrelated to volcanic activity, reassuring the public yet emphasizing preparedness.
Authorities expect the seismic events might continue for days or even weeks. Preparations for evacuation were established, with emergency personnel on standby for potential rescue operations. With each passing hour, the effects of the recent quakes left tangible concerns for islanders and tourists alike, affecting daily life and the usual tourism flow.
While caution has now become part of the local routine, authorities assert Santorini remains safe and urge residents to remain calm and adhere to safety recommendations. “Absolutely not. There may be some seismo-volcanic activity, but there is no chance of eruption,” Lekkas reassured the public, focusing on the need for vigilance rather than panic.
Authorities have called for strict safety measures, and the situation continues to be monitored closely, with updates expected as the seismic activity evolves. The people of Santorini are now grappling with the uncertainties of living atop one of the world’s most stunning — yet unpredictably active — geological marvels.
