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.

Santorini has been hit by a series of underwater earthquakes, leading the Greek government to declare a state of emergency. The most recent tremor, measuring 5.2 on the Richter scale, struck late Wednesday.

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.
