Yet another earthquake struck the area between Santorini and Crete in the early hours of Saturday, measuring 4.5 degrees on the Richter scale, according to the Athens Institute of Geodynamics.
This was the third tremor at the same spot in as many days, causing justified concern among citizens on both islands in southern Greece.
There was no damage or injuries reported.
On Thursday there was a 5.3 R quake followed by a 5.2 R tremor on Friday.
Seismologists, however, say they are not worried by the seismic sequence as they suggest that it serves to defuse the energy stored some 30 kilometers from the surface, where the center of the quake was.
Santorini citizens even expressed worries about a possible awakening of the island?s volcano, but Greek experts answered that although there has been some irregular behavior by the volcano, there are absolutely no signs linking it with the week?s tremors.
