Greece’s government declared a state of emergency on Santorini on Thursday after hundreds of undersea earthquakes shook the resort island for nearly a week. The ministry of civil protection’s announcement will provide authorities faster access to state resources.

Nearly 15,000 people have fled their homes in Santorini since Sunday and on Thursday night a 4.6-magnitude quake struck the sea between Santorini and Amorgos

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.
