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.

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

Since last week, thousands of residents have left the island by plane and ferry, as hundreds of earthquakes continue to shake the region.
