Experts say the Greek island of Santorini has been hit by more than 1,000 earthquakes, but they're not linked to the region's active volcanoes.

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.

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.
