Hi Jon,

For an excellent overview of global tectonics, there is a new version 
of the This Dynamic Planet poster available here:
http://www.minerals.si.edu/tdpmap/.  The PDF version is huge, but 
once downloaded would be very helpful via the zoom-in tool of Adobe reader.

During the past few years the USGS has produced a summary posters 
following the most significant earthquakes.  They are very helpful in 
providing insight into the tectonics of each region.  For example, this poster:
ftp://hazards.cr.usgs.gov/maps/sigeqs/20020325/20020325.pdf  was made 
following a 2002 magnitude 7.4 event in the Hindu Kush.  Again, the 
pdf format is large, but includes all of the details when the zoom-in 
tool of Adobe reader is used.

Links to all of the posters are included here:

Cheers,
John
