Greece’s government has declared a state of emergency on Santorini after hundreds of undersea earthquakes shook the resort island for nearly a week.

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

Tourists continued to flee the Greek island of Santorini on Wednesday — a fourth consecutive day of exodus sparked by a series of earthquakes that have rattled the incredibly popular European vacation destination.
