ATHENS, Greece — Greece’s government declared a state of emergency on Santorini on Thursday after hundreds of undersea earthquakes shook the resort island for nearly a week.

The Greek island of Santorini is facing a crisis after a powerful 5.2-magnitude earthquake struck on Wednesday evening. This follows an alarming series of tremors, with experts recording over 6,000 quakes in the Aegean Sea since January 26.

Experts say the Greek island of Santorini has been hit by more than 1,000 earthquakes, but they're not linked to the region's active volcanoes.

Repeated earthquakes are rattling Greece’s volcanic island of Santorini. Scientists say the quakes aren't related to a slight increase in volcanic activity that has also been registered recently.

A fresh series of quakes hit the Greek island of Santorini early on Thursday, part of an unprecedented seismic wave that has baffled scientists and led to a mass exodus of residents. Schools on more than a dozen islands in the Cyclades island group in the Aegean Sea have been shut as a precaution until Friday,

Greek officials are warning those on the popular tourist island destination of Santorini to stay alert in the coming days due to increasing seismic activity which could mean a strong earthquake is possible.

A series of earthquakes on Santorini has prompted thousands of people to leave the Greek tourist island since early 2025. Against this backdrop, some social media users were sharing old, out-of-context images and wrongly linking them to the tremors on the island.

Hundreds more people were expected to leave Greece's Santorini island on Wednesday as tremors shook the popular summer tourist destination for a sixth day. About 6,000 people have left on ferries and planes in recent days as hundreds of small quakes were registered in the surounding sea,
