Repeated earthquakes are rattling Greece’s volcanic island of Santorini. Scientists say the quakes aren't related to a slight increase in volcanic activity that has also been registered recently.

More Greek islands closed schools Tuesday as hundreds of earthquakes rattled the Aegean Sea, while a handful of hardy tourists enjoyed having Santorini’s stunning views to themselves. Thousands of residents and seasonal workers have left the Cycladic Islands as hundreds of quakes up to magnitude 5 were recorded in the volcanic region since Friday.

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.
