The Greek island of Santorini is being rattled by dozens of tremors, prompting authorities to close schools and airlines to announce additional flights on Monday to help people leave the popular tourist destination.

Thousands of locals flee the picturesque island as experts say rolling tremors ‘not linked to volcanic activity’.

Greek Prime Minister Kyriakos Mitsotakis appealed for calm as 200 earthquakes have left the residents of Santorini island, and its neighbours in the Aegean Sea, rattled, Al Jazeera reported on Tuesday.
