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.

Thousands of locals and travelers have evacuated the Greek island of Santorini amidst a spike in seismic activity.

A strong earthquake has been recorded between the Greek islands of Amorgos and Santorini, after days of consecutive tremors in the area. More than 11,000 people have already left Santorini with around 7,000 departing by ferry and 4,000 people leaving by air.

Residents and visitors have been advised to avoid large indoor gatherings and areas where rock slides could occur.

The latest of hundreds of earthquakes have rattled the volcanic Greek island of Santorini after the strongest one so far with magnitude 5.3

The popular Greek tourist island of Santorini has experienced thousands of near-constant earthquakes since Jan. 25, prompting more than 13,000 of the island’s 15,500 residents to leave the island, according to The New York Times.
