I did not feel it, people about 30 miles N. of me did but it was felt from Benson, Az to parts of El Paso, TX from reports from friends.
There was what sounds like a fairly major quake years ago in Southeastern AZ, Mexico:

The actual location of the quake and the aftershocks were on the Lazy B ranch that is the title of Sandra Day O'Connor’s book.
One aftershock was less than 1/2 mile from their ranch house.
