Camlacherin,

I do believe subsidence can occur (It logically follows)
but there may be a number of geological and depth factors
to consider.
I am not qualified to discuss these, but I am sure somebody will address them for us.

What I am surer of is that any subsidence issues, will be minor compared with the water and salinity issues with CSG.

Lets hope the CATALYST works(ie. lights the fuse!!)

Cheers,

Boz
