Schools were closed and emergency crews deployed on the volcanic Greek island of Santorini on Monday after a spike in seismic activity raised concerns about a potentially powerful earthquake.
Precautions were also ordered on several nearby Aegean Sea islands — all popular summer vacation destinations — after more than 200 undersea earthquakes were recorded in the area over the past three days.
“We have a very intense geological phenomenon to handle,” Prime Minister Kyriakos Mitsotakis said from Brussels, where he was attending a European meeting. “I want to ask our islanders first and foremost to remain calm, to listen to the instructions of the Civil Protection (authority).”
Mobile phones on the island blared with alert warnings about the potential for rockslides, while several earthquakes caused loud rumbles. Authorities banned access to some seaside areas, including the island’s old port, that are in close proximity to cliffs.
“These measures are precautionary, and authorities will remain vigilant,” Civil Protection Minister Vasilis Kikilias said late Sunday following an emergency government meeting in Athens. “We urge citizens to strictly adhere to safety recommendations to minimize risk.”
