While Greece is in a highly seismically active area, it's extremely rare for any part of the country to experience such an intense barrage of frequent earthquakes.

A state of emergency has been declred in Santorini, a volcanic island and popular tourist destination in Greece, as an 'earthquake swarm' that began earlier this month continues. Since 31 January, more than 800 tremors with a magnitude of three and above have been recorded.

Thousands of locals flee the picturesque island as experts say rolling tremors ‘not linked to volcanic activity’.
