Greek officials have declared a state of emergency, and tourists and locals have fled the tourist island of Santorini amid earthquakes in the past few days.

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.

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.
