Your OP addressed the unusual nature of the Reno area fault (deep hypocenter). Now the LA Times is reporting on a swarm of shallow quakes.

As you know, the Basin & Range is an extensional province, caused, I believe, from the effects of the shallow subduction of the Farallon plate. Extensional block faulting tends to run from shallow to moderately deep, does it not?

What's your take on this?
