Yes. I must admit that in my haste I was being flippant (always a
mistake). Since the moment tensor is symmetric, you cannot, from the
CMT alone, differentiate the fault plane from the auxiliary. That
ambiguity vanishes, however, for a finite fault---hence all the papers
on finite fault inversions in the special January '07 issue of BSSA.
To give Scalera and his reviewers their due, that special issue came
out at the same time as Scalera's paper, so they may not have been
aware of the overwhelming evidence for a thrust source.


I read some of the abstracts and a couple of papers. So, there was
overthrusting of the Burma area over the Indian ocean. Very good.
But do you understand why?


Fig 4 is a throwback to the old Wegener model of continents ploughing
through oceanic lithosphere, it is inconsistent with the idea of
subduction.

Pardon me? It is an illustration of the elastic rebound model at
subduction zones.
