I think this is very much business as usual. That is not to say it couldn't be catastrophic but I do think it is part of a natural cycle. It could wipe us off the planet but I feel nothing out of the ordinary for the planet. They say the whole crust of the earth has shifted all at once in the distant past and will again. We may be headed to that....or not.
