Hi, 2 cents worth, There are many seismic arrays available via the
Automatic Data Request Manager, (AutoDrm). If you are interested
see    http://www.iinet.net.au/~ajbv
Also  http://orfeus.knmi.nl/
Also http://www.pidc.org/networksbox/Network.html

I have, on occasions, downloaded the seismic array data  for a
specific time period. Its easily done.
