Hi All- A little more info on the PMD/MET  seismometer.  I first heard of
it 2-3 years ago, as it was one of the PEPP (Princeton Earth Physics
Program) http://lasker.princeton.edu/education.html seismometers along
with the Guralp.  I believe ~9 of the ~90 PEPP seismometers are the PMD
type.  I always called it the chemical seis for lack of a better name. 
The early PMD2's that PEPP has had, have not performed well.  However,
Tom Owens's South Carolina group, SCEPP, has had a good experience with
the newer three component PMD machines.  They have purchased around 40
3-component PMDs.  At this time you cannot run SCREAM (Guralp's software)
with these machines, though. I am not sure about WinQuake- As good as
Scream is, many PEPP people prefer WinQuake!!!!!


PMD or MET:

US Educational Seismic Network (USESN):
BTW, I attended the IRIS annual meeting in June and volunteered to serve
on the US Educational Seismic Network (USESN) Committee.  It consists of
9 states, which have their own high school seismic networks, PEPP
related, and the PSN.  I believe Gary Simila, seismologist from Cal State
Northridge, suggested  PSN be part of the USESN.  Since I was familiar
with the PSN, I seconded the motion and described many of the PSN
activities.  The main focus of the USESN is to effectively promote
programs for educational seismographs in schools.  No buddy does it
better than you guys!

Nevada Educational Seismic Network (NESN):
I am working on putting together a 20 site network for Nevada high
schools which I hope to have up and running by the beginning of 2002. 
Funding comes from the Nevada Earthquake Safety Council and the Nevada
Public Agency Insurance Pool. The planning has been going on for over a
year,  and much of the design and components has come from the PSN and
Larry Cochrane.  These sites will be much cheaper per site (~$500) than
the PEPP (~$2500) sites.....Jim
