Thanks Zhenming.  I hope any family you might have in the region are safe.

One thing we've noticed around here is that in all the photos and film 
seen, there is no reinforcing steel protruding from the collapsed 
concrete.
One photo we saw (Section A, page 8, USA Today, May 14th) showed large, 
nearly regular-shaped slabs of what appeared to be concrete...the edges 
all looked smooth and straight, as if they might have been pre-cast blocks 
assembled on-site.

I would like to share with you all the Chinese National seismic design map 
(PGA with 10% PE in 50 years). This may explain one of the reasons that so 
many schools and hospitals collapsed in the Wenchuan earthquake. 
 
Thanks.
