In a previous post Darryl Okahata says...
Out of curiousity, does the midwest have any kind of earthquake building
codes?


IBC2003 deals with the country as a whole. Seismic design parameters
required are based on ground acceleration values determined by USGS and
are generally based on a statistical model of 10% chance of recurrence
in 50 years.

What all this means is that many buildings in the midwest and along the
east coast are going to be subject to at least some of the seismic
design provisions of IBC2003.
