Dan, I didn't say it did not happen, I just said that I personally don't see the phenomenon.That is to say that my geological skills are nil to none. I read your links, and at least now I have a rather vague ideea of the phenomena involved.

What I still cannot see is why no one bothered to apply the methods they use in the Netherlands for preventing flooding and further land compactification. It is not that they didn't know this was happening in NO and similar regions, and it is not that they never heard of the Netherlands.

But maybe this means asking too much from below room temperature IQ bureaucracy, as Amaranth said.
