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.

A state of emergency for Santorini has been declared for almost a month as more earthquakes struck the ocean around the Greek island. More than 12,000 people are reported to have evacuated by air and ferry as authorities reported that earthquakes are being recorded on minute-by-minute intervals.
