No Shaw, I carefully explained above, summarising anything of the complexity of the subject raised in a couple of paragraphs is not going to hack it. I also said not everyone has the same starting point in terms of knowledge. If you keep on trying to fault everything I posit then obviously the discussion is going to Start to become a little more technical.
My particular interest is in borehole stability and how it is influenced by both regional stress and the mineralogy of clays. The latter being of particular difficulty because of their unique characteristics. Having looked at numerous failures(faults) in core boxes, in the field, and studied shear surfaces under the microscope I have a knowledge that is of both limited appeal and distribution. That is a fact of life. However it is in a way related to seismic activity as it is a study of rock failure.
If you feel it is too technical for mudcat you had ample opportunity to raise the issue earlier, or you could simply stop trying to create argument(your favourite tactic). Rock failure is a subject I have a deep interest in.
I see in one of your warblings about volcanoes you either swallowed wikipedia or you were out to impress A Level students of physical geography so I suspect you are equally guilty. The difference is that I am trying to give a simplified explanation whereas you are merely trying to demonstrate your superior erudition, as per usual.
