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.

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.

Earthquakes have continued to rattle Greece’s volcanic island of Santorini every few minutes through the night and into Wednesday. Authorities have bolstered their emergency plans in case the hundreds of tremors over the past few days are a harbinger of a larger quake to come.
