We have come across some Teledyne Geotech S-500 short period
seismometers that spent many years on the side of Turtle Mountain in the
Crowsnest Pass, Canada (www.frankslide.com/info.html). We're currently
re-instrumenting the mountain and are contemplating re-installing these
old S-500s on some spare channels (our focus is on seismicity of much
higher frequency). Are seismometers of this vintage still trustworthy?
They've been buried (unprotected) in soil for 15 years. They look ok
externally, but we haven't bench tested them (don't have the pin-out).
I don't have the specs/manuals for these seismometers (I'm sure someone
at Geotech Instruments can help). If anyone off-hand knows the
specifications for these seismometers I would appreciate a note.
