More Greek islands closed schools Tuesday as hundreds of earthquakes ratted 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.

Mitsotakis's remarks come as many people in Santorini spent Sunday night outdoors, amid fears of potential damage to buildings during the quakes. Some focal points of the tremors have been recorded at a depth of just 2km (1.2miles) below the surface.
