Possibly, but I'm wondering what would there be to be done even if they=20 are aware of it all? I don't really know anything about such things (fortunately in this=20 country we have little need to) but your analysis seems quite plausible=20 (to me at a quick read - not looked at any maps) I understand there is some benefit in predicting these things, but I=20 imagine politics/economics will often be a large(r) factor in deciding=20 what to actually do about them. I guess if you are going to do something=20 like evacuate millions of people and give up (various levels of,=20 depending on area) lucrative land then some pretty concrete evidence=20 would be needed. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
