They haven't really reached the actual fault rupture yet. If we find the towns in the actual fault valley are powdered, then this earthquake is right up there, as a valley thrust 'super quake'. Total numbers of casualties may be limited by the thin population density. As I have said before, there's no way to design for the full impact of a super quake, on the hanging wall.
But I still think that when they write this one up, it will have been found to have ruptured right to the bottom of the crust.
