[CIG-LONG] Faults do not depart away from the axis

[Taichi SATO]

Hi,

I still have problem with the dike hill of 
mid-ocean ridge modeling.
But I found another problem. Faults initiated at 
the axis do not depart away from the axis.

I think this is the same problem written in the 
supplemental paper of the Buck et al., 2005, Nature.
I picked up the sentences from the paper,

---------
  Accumulation of plastic deformation in the dyke 
tends to lock the location of tectonic faulting at 
the base of the dyke and does not allow the faults 
to depart away from the axis as is observed. To 
solve this problem strain accumulation in the dyke 
is limited to smaller amount than the initial 
weakening necessary to form a fault (5 MPa of 
cohesion reduction). This way a fault forms and 
can move away from the axis.
----------

I have no idea how to apply this solution to the Gale.
Would you give me some suggestion?

Sincerely,

Taichi
