February marks the unofficial start of the tourist season in the Greek island of Santorini - when the first cruise ships are due to arrive and the Easter holidays approach. But with thousands of earthquakes shaking the island since January and experts unable to say when they will end,

Scientists have detected several thousand earthquakes, the vast majority of them with small magnitudes, in just over two weeks near Greece’s volcanic island of Santorini.

On Monday, a magnitude 5.3 earthquake struck in the sea area between Santorini and Amorgos in the Cyclades. This seismic event, noted as the strongest in recent weeks, resulted in no casualties or damage reported. The epicenter of the earthquake was located in the sea area 14 kilometers south-southwest of Amorgos.

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.

Greece has declared a state of emergency on Santorini after hundreds of undersea earthquakes shook the resort island for nearly a week.

Authorities declared a state of emergency on a second Greek island Wednesday as a series of earthquakes continued to rattle the south-eastern Aegean Sea region. The emergency measure announced on the island of Amorgos follows a similar decision for nearby Santorini on Feb.
