Hundreds more people were expected to leave Greece's Santorini island on Wednesday as tremors shook the popular summer tourist destination for a sixth day.

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.

Greece is preparing for any scenario but experts are optimistic about the tremors that triggered an exodus of residents and visitors from the Aegean Sea island of Santorini.
