Greece’s Aegean islands, including Santorini, Amorgos, and Anafi, are experiencing an intense and unusual earthquake swarm, with tremors reaching magnitude 5.3.

Over two-thirds of Santorini’s residents have voluntarily left, and authorities have declared a state of emergency, closing schools and discouraging large gatherings.

Scientists are baffled by the erratic seismic activity, which lacks a clear mainshock and appears tectonic rather than volcanic in origin.
