[CIG-SHORT] Ask for the instruction on modelling the slip distribution

[Brad Aagaard]

Yangmao,

If you want to model geodetic observations from coseismic slip, you can
use PyLith to construct the Green's functions. PyLith is not an
inversion code, so you will need to do your own inversion.

Regards,
Brad
