Hundreds of earthquakes that have rattled the Greek islands since last week have prompted the evacuation of thousands from the tourist hotspot of Santorini.

Schools will remain closed on Monday, and people on the island are being instructed to drain swimming pools, avoid large gatherings inside buildings and stay away from abandoned buildings.

Hundreds of people scrambled to leave the Greek island of Santorini by ferry Monday after an increase in seismic activity raised concerns about a potential powerful earthquake.
