Repeated earthquakes are rattling Greece’s volcanic island of Santorini. Scientists say the quakes aren't related to a slight increase in volcanic activity that has also been registered recently.

A 5.3 magnitude earthquake struck near Santorini, Greece, the latest in a series of temblors near the popular tourist destination.

Thousands of residents are fleeing Santorini after hundreds of earthquakes were recorded near the Greek island in the last 48 hours. About 9,000 people have left the island since Sunday, with additional emergency flights scheduled to leave on Tuesday.
