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, the University of Athens' crisis management committee said Tuesday,

The Greek island has a long history of earthquakes, but what is causing the recent series of quakes has scientists perplexed.

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.

Earthquakes are still rattling Greece’s volcanic island of Santorini every few minutes as authorities bolster their emergency plans in case the hundreds of temblors in recent days are a harbinger of a larger quake to come.

The Greek island of Santorini is still shaking. Tourists and locals have already fled to the mainland, while emergency services on site are ready to intervene. An earthquake was even felt in Athens.
