I don't have time to work on this right now, but a couple of points:
1) Faulting: you have the meaning of hanging wall and footwall reversed, i.e. the hanging wall of a normal fault subsides.
2) Isostatic rebound: This name is misleading. Loading of the Earth's crust (technically this should be "lithosphere", in this context) by glaciers, sediment, etc., causes isostatic subsidence. Unloading when this weight is removed causes isostatic uplift, which is then called isostatic rebound. A better name for the section would be "isostacy", or "isostatic subsidence", because "isostatic rebound" is actually uplift (the opposite of subsidence)
3) Gas Extraction: Probably this section should be "pore fluid extraction", to include gas extraction (e.g. Mississippi Delta) but also groundwater extraction (e.g. Mexico City) as causes of subsidence.
Good start though. I will try to get back and do some edits when I have time.
