Thousands flee Santorini as 5.2 magnitude earthquake rattles Greek island - The 5.2 magnitude quake followed two smaller tremors and was recorded at 21.09 local time

Experts say the Greek island of Santorini has been hit by more than 1,000 earthquakes, but they're not linked to the region's active volcanoes.

Earthquakes rattled Greece’s volcanic island of Santorini every few minutes overnight and into Wednesday as authorities bolstered emergency plans in case the hundreds of temblors over the past few days are a harbinger of a larger quake to come.
