After the first few days, it became a cluster and not foreshocks. The earthquake hazard is now at background, and everybody can move back again, if they are used to living on the edge. The cluster is activated by fluid motion, and now it shows that it is very 'rough' in terms of the fault texture.
The main hazard for faults is 'bathtub slip' or stick-slip, which requires a very smooth fault. Every cluster event smooths out the fault, but there may be many of these.
Of note, a nice earthquake just popped over in Italy. The location of the next damaging earthquake is now random. That said, we still have the normal odds that a damaging earthquake could pop off under Santorini tomorrow, like anywhere in this area. If you move back to your lovely stone pile, don't blame me if you become a pancake tomorrow, but this cluster isn't telling you anything.
The normal odds are showing a damaging earthquake for anywhere in this zone, of about 1 in 100, or 500, for any given spot. These are the same odds for a house-wiping tornado in NA, or something horrible in California -fire, flood, earthquake. Go back and enjoy your life of danger. I am estimating 5 cm/sec on solid rock, and 40 to 80 on soft soil. It is my contention that everybody should just breeze through these levels anywhere on earth. That requires steel construction and screw piles down to rock.
ps the Greeks were about to be put on my 'Smarty List', but they've been installing, and there is no improvement. Thus, I have to assume they are doing it wrong. Taiwan was on the list, but they allowed a building made of tin cans to be exposed to several earthquakes, until it fell.
