In light of the huge amount of quakes that have been shaking the Dodecanese Islands in Greece, I did a bit of research.
Three plates converge in the area, the Eurasia, Africa, and Arabia plates. The smaller Aegean Sea plate is mostly effected by the Africa plate.
There have been some very large slip/strike quakes there in the past.
The magnitude 7.8 earthquake of July 9, 1956, south of Amorgos, produced a large tsunami that affected the entire Aegean Sea.

A huge earthquake in 226 BC on the island of Rhodes is credited with toppling the Colossus of Rhodes statue.

As of last count, there have been 28 quakes there just today.
