ATHENS, Greece — 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, adding that a larger quake cannot be ruled out.

It welcomes around 3 million visitors per year, but between January 26 and February 8, the Seismology Laboratory of the University of Athens has registered a staggering 12,800 earthquakes in the Santorini-Amorgos zone, the strongest of these was last night at a magnitude of 5.3.

The emergency measure announced on the island of Amorgos follows a similar decision for nearby Santorini on February 7 after thousands of unusual tremors were registered in an undersea area

ATHENS : An earthquake of 5.3 magnitude hit the Greek island of Santorini late yesterday, officials said, the strongest yet of the thousands of tremors that have shaken the area, prompting thousands to leave. Felt as far away as Athens, the undersea quake caused neither damage nor injuries.

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,

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.
