The subsidence of coastal Louisiana has nothing to do with plate tectonics. It is entirely man made. There are two main causes. The first is anti flooding programs on the Mississippi River caused the river to drop its sediment load up river and prevented the river from carring much of it down river to be deposited in the Mississippi delta area. Sediments naturally erode, compact and subside once deposited. When the river was carrying its natural sediment load deposition balanced subsidence, erosion and compaction. Now the delta erodes and settles faster than it is being replenished.
The second is withdrawal of natural gas and oil from their reservoirs cause the overlaying ground to settle.
Being from Louisiana and working in the engineering industry. I can say that is basically spot on. Other issues with the delta too, is the fact it will make hurricane landfalls more severe. Evidence that YES man can damage the environment.
