A series of earthquakes near Santorini, Greece has prompted tourists to flee the area and the country to declare a state of emergency.

More than 11,000 people have already left the island of Santorini following a series of tremors in recent days.

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.
