More Greek islands closed schools Tuesday as hundreds of earthquakes ratted the Aegean Sea, while a handful of hardy tourists enjoyed having Santorini’s stunning views to themselves

Thousands of people are fleeing the Greek island of Santorini as increased seismic activity spurs fears of a more powerful earthquake at the site of one of the largest volcanic eruptions in history.

Santorini's earthquakes are intensifying as a rare earthquake swarm continues to rattle the Mediterranean's Aegean Sea. The earthquakes are probably caused by faults rather than volcanic activity.

Repeated earthquakes are rattling Greece’s volcanic island of Santorini. The quakes are prompting authorities to dispatch rescuers with tents, a sniffer dog and drones and to shut down schools on four islands.
