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.

Earthquakes are still rattling Greece’s volcanic island of Santorini every few minutes as authorities bolster their emergency plans in case the hundreds of temblors in recent days are a harbinger of a larger quake to come.
