PSHA using background seismicity in OPENQUAKE

[muetc...@gmail.com]

Hi,

I have G-R parameters a,b information and GMPE's input parameters.

I want to model seismicity as a point source, using G-R ab values distributed in 0.1x0.1 grids. Is it possible to model easily in openquake?

I am beginner so need an idea to start with.

Thanks.
