Past tsunamis have hit Israel’s coast, and with Santorini’s seismic activity at an all-time high, the risk of another wave is being taken seriously. Authorities remain on high alert, as the region watches and waits to see what happens next.

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.

Greek officials are warning those on the popular tourist island destination of Santorini to stay alert in the coming days due to increasing seismic activity which could mean a strong earthquake is possible.
