Is a lot of this on one large fault, and is it gently-dipping or steeper? Or, is it on a whole bunch of faults? The area of earthquakes seems to be expanding. Is there something deep that is creeping and loading shallower faults?

I've been curious about that as well. But I've not bothered to try to make a cross section because this data is all preliminary and/or automatic solutions. It would be better to use "relocated" quakes, and I wonder if anyone is going to do that.

I think the 'fuzziness' of the distribution is due to the preliminary solutions. I suspect that once relocated the quakes may line up quite well along the fault.
