A series of earthquakes near the Greek island of Santorini have resulted in significant precautionary measures, leading authorities to shut down schools and dispatch rescue teams equipped with sniffer dogs. Since early Friday, over 200 tremors have been recorded, with the strongest reaching a magnitude of 4.6, according to the South China Morning Post. Expert analysis confirms that these seismic events are not related to the volcanic activity of Santorini, despite the area's historical significance as the site of one of the largest eruptions in history.

The tremors have left locals anxious, prompting officials from the Ministry of Climate Crisis and Civil Protection to convene daily meetings regarding safety protocols. Following a meeting on Sunday, authorities decided to close schools on Santorini and the nearby islands of Amorgos, Anafi, and Ios on Monday. Moreover, residents and hotel owners were advised to drain their swimming pools to mitigate the risk of structural damage from potential strong quakes, as large volumes of water could destabilize buildings. This advice comes amidst heightened concerns for safety as the islands are characterized by steep cliffs, particularly in the main town of Santorini, which is built on a precarious cliffside.

Another emergency meeting is planned at the prime minister's office with the chief of Greece's armed forces and other key officials to discuss ongoing safety measures. In response to the increased seismic activity, the fire service has mobilized additional contingents of rescuers, including sniffer dog units. These teams have set up temporary shelters in open fields to help prepare for potential emergencies.

Residents have been cautioned to avoid large public gatherings and to remain vigilant for rockfalls as they navigate the islands. Experts have noted the impossibility of predicting if the ongoing seismic activity could lead to stronger quakes but mentioned that the region could potentially experience a magnitude-6 earthquake.

While mild seismic events have been detected in Santorini's submarine volcanic caldera since September, the situation is under close scrutiny. The most significant tremor in the caldera was recorded at a magnitude of 3.8 on January 25, after which seismic activity subsided.

Historically, the Santorini volcano's eruption around 1600 B.C. had catastrophic consequences, burying an ancient town and causing massive earthquakes and tsunamis that affected areas as far as Crete and Egypt. Given its historical context and proximity to populated regions, the Santorini volcano is classified as one of 16 critical volcanoes globally that are subject to continuous monitoring due to their eruption histories and potential hazards.
