Hi Bonnie,

How do you "read" the PSN postings?  Do you use a translator from
text to voice?  The browser-based alarm I mentioned earlier would 
notify you of new earthquakes on the NEIS finger listing, which is 
on the NEIS web site here:

http://wwwneic.cr.usgs.gov/neis/bulletin/bulletin.html

The alarm has a graphical interface requiring a mouse click to
reset it after an earthquake, so that may be a problem.  Also,
it would go off for any reviewed solution anywhere in the world!

Another option would be to set up a seismic system using Larry's 
AD board and software.  You could use a 4.5 Hz geophone for 
detecting local events.  I haven't used his program, so don't
know for sure if you could set up the trigger settings to 
alarm on a local earthquake but not a bus.  Birds may be smarter!

Also, Larry can let you know if the system has an audible alarm.

Sounds like an interesting project.

John
