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.

Emergency services were deployed in readiness and schools were closed after more than 200 temblors struck in the Aegean, near Santorini, within 48 hours.

The Greek island of Santorini is being rattled by dozens of tremors, prompting authorities to close schools and airlines to announce additional flights on Monday to help people leave the popular tourist destination.
