For several days, Greek authorities have introduced several measures after several minor earthquakes near the Greek island of Santorini.
On Thursday, the authorities declared a state of emergency that will last until March 3.
11,000 people have left the island, and schools have been closed.
There have been no injuries after the earthquakes and authorities say the measures are precautionary.
Santorini is located on top of a volcano that has not erupted since 1950. The earthquakes are not believed to be related to volcanic activity.
