Earthquakes are still rattling Greece’s volcanic island of Santorini every few minutes. The temblors continued through the night and into Wednesday as authorities bolstered emergency plans in case they herald a larger quake to come.

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.

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.
