Hi Andy,
Actually monitoring water in a well may be more useful in
predicting earthquakes. See =

If you want to record earthquakes I suggest you build a Lehman style
seismometer. This is a simple way to get started and it is very =
rewarding. You
can get much assistance with this group. Here is a start =

Subject: sensor in a well
Hi PSN list,
I have a copy of The Amateur Scientist by C.L. Strong 1960. It is a =
collection
of projects and articles from The Scientific American. In the Earth =
Science section
are several articles on seismology. It was this book that first got me
interested in the subject. One article by Elmer Rexin describes using a =
float
in a well to detect seismic events.
I happen to have a well under my house, it is cut into the limestone, =
the water
surface is 10 Metres below the floor of the cellar. I know of one =
sink-hole on
the plateau above the village so It is possible that the well could be
connected to an aquifer in the limestone hillside. The well in the =
article did
have a connection to lake Michigan and so acted as part of a giant
"U-tube".
Anyway, the point of all this is to ask if anyone thinks there could be =
an
advantage in setting up some form of sensor in the well, and if so, have =
you
any ideas?
Regards,
Andy
