Tourists continued to flee the Greek island of Santorini on Wednesday — a fourth consecutive day of exodus sparked by a series of earthquakes that have rattled the incredibly popular European vacation destination.

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.

Greece is preparing for any scenario but experts are optimistic about the tremors that triggered an exodus of residents and visitors from the Aegean Sea island of Santorini.
