Almost all of the listed regions are places that are active quite often and have experienced a number of large quakes in recent years. I'm eyeing Greece and the Eastern Mediterranean Sea region now. There has been more activity than usual taking place there lately. This may include Eastern Turkey. Major metropolitan areas would include Athens and Istanbul. A large quake may also not happen at all there. It is just a place of possible concern at this point.
In terms of activity in Southern California, so far, more or less. More mag. 3-4+ is due here anytime or within the next week or two. Something more significant could be around the corner. However, there have been 4-6 hour gaps between mag. 1+ EQs here in Southern California South of the Tehachapi Mountains. The activity here has been somewhat low this week, but it could ramp back up again at any time.
There also could potentially be more sizeable aftershocks in the Little Lake sequence anytime now or later into the weekend. There could also be more activity taking place in the Pacific Northwest as well as Southern Nevada.
