Schools in Santorini, Ios, Anafi, and Amorgos will remain closed at least until February 21, 2025, as the Greek government prepares for another meeting to assess seismic risks in the Aegean Sea near Santorini. Over 1 300 earthquakes were recorded with a magnitude above 3.0 in the sea area near Anydros since the beginning of the month, with the strongest reaching M5.3. The government also announced plans to build an emergency escape port in Santorini in addition to the new port under development.

On January 18, two M5.1 quakes were registered between Santorini and Amorgos, shaking the area with enough intensity to be felt across multiple islands.
