Hi Bob;

I suspect those devices cost thousands of dollars
because it is the drive of most people who
deal with Government to rip Uncle Sam off.
Because Uncle Sams makeup is always changing
they seem able to get away with it.
These items if they are borehole need to be 100
or more feet down and who has the money
in the amateur world to get a driller
to drill such a hole.
I cant even afford to get a new drywell
if I might ever need one.

Maybe I should have included the idea
in my original thought as being something
we might build or obtain for our own use.

The USGS had these 500# seismometers that are
quite good and used to put them all over
the earth. If I had a decent place to keep one
Id try to get one of those.
They are quite large and need to be kept
out of the dampness and away from temp changes.
You cant easily move one from one place to another.
I think these 500# devices were used for that
nuclear thing you talk about.
You should have special underground building
just for this seismometer.
