More than 11,000 people have already left the island of Santorini following a series of tremors in recent days.

Greece has declared a state of emergency on Santorini after a series of earthquakes shook the popular tourist island this week and prompted more than 10,000 residents and workers to evacuate.

A 5.2 magnitude tremor has been detected between the Greek islands of Santorini and Amorgos — the most powerful recorded since activity started on on January 31.
