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’.

Schools will be closed Monday on the iconic Greek island of Santorini after a series of 200 earthquakes shook the popular tourist destination in recent days. Authorities have also advised residents to avoid large indoor gatherings and steer clear of multiple ports, including the old port of Fira, just below the island’s capital.
