Hi Bob,  The book is  "Earthquake Prediction"  by Haroun Tazieff.  Very well 
written. However it is sparse on the actual layout of sensors and 
amplification required.  It contains a fascinating theory of why it works so 
well also.  They claim 90% success for regions that have been "calibrated",  
that is, one or more seismic signals have been received that indicate how a 
region "responds"  These fellows have been around and have been having 
success in several European countries since about the mid '80s.  Sure would 
like to give it a try.  In WA  there are several regions that are regularly 
active.  Mike.
