[CIG-SEISMO] [Specfem3D Cartesian]- Using a CMTSOLUTION source to trigger a critically-stressed fault

[Ge Li]

To Whom It May Concern:

 

I’m a PhD Candidate in geophysics at McGill University. Currently I’m using

Specfem3D Cartesian for my research. 

I’m wondering is it possible to trigger an earthquake on a fault using a CMTSOLUTION source?

I tried several simulations by setting a critically stressed fault and a CMTSOLUTION point source.

The source (Mw~6 Right-lateral strike slip) was located about only 1km away from the fault surface.

But it turned out the stresses on the fault surface(dynamic slip-weakening) remain unchanged. 

Based on these tests, I supposed that a CMTSOLUTION won’t change the stress level on a fault surface. Is it correct? 

Or did I miss something here?

 

Thanks! I’m looking forward to your reply!
