Ios became the fourth island in the Aegean to be placed under a state of emergency on February 15, following the trend set by Santorini on February 6, Amorgos on February 12, and Anafi on February 13, due to the ongoing seismic activity in the region since late January 2025. 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.
