Judging by the epicenter of this one in relation to the epicenter and finite fault model (shown below) of the quake two weeks ago, I'd say this is a "cascade failure".
As of this writing, there is no FFM for this quake, but the focal mechanism is consistent with another thrust. I expect the new FFM to fill an area to the east of the previous fault model.
The image below is the finite fault model of the M7.8 on April 24th, not this new quake.
Although this was 'only' and M7.3, the region is already so damaged that the result could be just as devastating.
