Next question for the experts: I have checked out the USGS site for some time now and have noted that there are often quakes in the same region for several days (aftershocks) but I have noticed that most of them are recorded at close, yet varying depths. In this latest quake however, I have also noticed that *ALL* of the aftershocks as well as the main quake are at a depth of exactly 10 kilometers. Is that normal, and why?

Yes that is normal, you are mostly likely to get quakes around the same depths for a given area because of what the ground is made of.

It was like 10 years ago I took the geology classes though so I'm an amateur at best.

If you want to figure out more about earthquake depths
earthquake.usgs.gov...
I would also bet the main reason you don't see any changes in depth is because the tension was not actually released yet so these aftershocks would be like a person trying to get their car out of a parallel parking spot by ramming the person in front and back of them because they were too close. Unless those other cars move you would just keep hitting them in the same place on the bumper.
