Santorini has been placed in a state of emergency following a series of undersea earthquakes, the strongest of which registered a magnitude of 5.2 on Wednesday, February 5, 2025. The ongoing seismic activity, centered between Santorini and Amorgos, has raised concerns among experts and local authorities.
Escalating Seismic Activity
Since the initial tremor, Greece’s Geodynamic Institute has recorded over 100 earthquakes of varying magnitudes. Several of these quakes exceeded 4.0 in magnitude, occurring in the early morning hours between 04:00 and 05:30. The continuous seismic activity has led to heightened alertness among both seismologists and residents.
Seismologist Efthymis Lekkas commented that this level of activity might be beneficial as it helps dissipate accumulated energy, potentially preventing a larger, more destructive earthquake. However, not all experts share this optimism. Vasilis Karastathis, Director of the Geodynamic Institute of Athens, emphasized that the seismic swarm shows no clear signs of subsiding. “We are still in the middle of the process,” he stated, warning that further significant tremors cannot be ruled out.
Emergency Measures and Evacuations
In response to the seismic events, Greek authorities have activated emergency protocols, deploying rescue teams and implementing safety measures. Schools in Santorini and nearby islands have been temporarily closed as a precaution. Authorities have also issued warnings about potential landslides and structural damage in certain areas.
As concerns grow, approximately 11,000 people have evacuated Santorini, with 7,000 leaving by ferry and another 4,000 by air. Meanwhile, officials are advising residents and tourists to remain vigilant and follow safety guidelines.
Potential for a Stronger Quake
Professor of Tectonic Geology and Geodynamics, Dimitris Papanikolaou, noted that a more powerful earthquake—potentially reaching a magnitude of 6.0—could occur. This possibility has led to increased monitoring of the region by experts, who are assessing whether the current seismic activity is an isolated swarm or a precursor to a major event.
Looking Ahead
Scientists continue to track the situation closely, evaluating whether the seismic activity will taper off or escalate further. As of now, residents and visitors in Santorini are urged to exercise caution, adhere to emergency guidelines, and stay updated on further developments. The Greek government remains on high alert, ready to respond should conditions worsen.
While the future remains uncertain, one thing is clear: Santorini and its neighboring islands are facing a period of heightened seismic activity that requires vigilance, preparedness, and ongoing scientific assessment.
