Santorini is shaken by frequent earthquakes, leaving residents and tourists on edge as experts weigh in on the situation. While there's no immediate danger of a volcanic eruption, concerns remain over the unpredictable seismic activity.

More Greek islands closed schools Tuesday as hundreds of earthquakes ratted the Aegean Sea, while a handful of hardy tourists enjoyed having Santorini’s stunning views to themselves. Thousands of residents and seasonal workers have left the Cycladic Islands as hundreds of quakes up to magnitude 5 were recorded in the volcanic region since Friday.

Greece lies in a highly seismically active part of the world, and earthquakes are frequent. The vast majority cause no injuries and little or no damage, but the country has also seen deadly quakes. Earthquakes can't be predicted, but authorities are taking measures as a precaution.
