Hi Chris,

I'm just displaying images that are generated at the USGS Albuquerque 
Seismic Lab
(ASL).  The 10 to 40 s band would be an interesting comparison, but I 
don't have the raw data
to generate such a plot.  I the data is available from 
ASL:  http://www.liss.org/software/connect.htm
so someone with the right filtering software could generate such a plot.

Cheers,
John
