In case you missed the lengthy discussion,
here's the website that displays the
seismic measurements from that station -
http://rev.seis.sc.edu/stations/TA/T11A?station_dbid=1586

There's another monitoring station SW of there
Code: TA.U11A
Name: Corn Creek, NV, USA
Location: 36.42 N, 115.38 W

And there's another on someone's property in Rach-town.
All curiously set up to monitor earth movement south
and east of a place where there may or may not be
a big boom test, if the politics ever work out.

You were the "OPERATION" game voice?
Yes. Take out wrenched ankle.

Uh   ...... wharze the geophones ??  can't see any geophones in either
of these pictures !

looks a LOT more like a geomagnetic setup of equipment ..... the white
cabinet  box , is typical of USGS geomag units .

earthquake sites are usually ( huge )  spider webs of linked
geophones, on a  splay of axis suitable for monitoring ground motion.
it takes numerous  ( dozens , many dozens )  vertical and horizontal
arrays to accomplish  this properly.

like this .........

even in my own personal system I have a grid of 11 sensors for both
vertical and horiz .   this doesn't look like anything I have seen
before (  and I have seen tons of them )  for earthquake measurement.


it does , however , look a  lot like the cabinet in the middle of this
page ...........
http://geomag.usgs.gov/observatories/fresno/


for this to " really " be useful for earth quakes  it seems to be
missing a LOT of equipment that is standard for such stations.
 

maybe the one ( without the white cabinet ) is measuring ground water
radiation and has a single  scint  probe buried in the water table !!
dunno, but  nothing there to suggest seismic  measurements  !!
