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.

Experts say the Greek island of Santorini has been hit by more than 1,000 earthquakes, but they're not linked to the region's active volcanoes.

Precautions were also ordered on several nearby Aegean Sea islands - all popular summer vacation destinations - after more than 200 undersea earthquakes were recorded in the area over the past three days.
