Here's another part of the New Madrid "aftermath game plan", boys and girls!  It's 153 pages and WELL WORTH your time to read.  (You may need a drink or two after going thru the report.)

Btw, pages 8 / 153 and 146 / 153 of the report (as would show in the tool bar - not the physical pages of the report) are truly staggering in their 'estimations.'  Also, there is reference - several times in the report - to a 2 a.m. to 2:30 a.m. event from one or more 7.7 initial shocks!

I'd have to say that this October 2009 report is far too lengthy and detailed for going into any 'exercise' in May.
