maybe the one ( without the white cabinet ) is measuring ground water

dunno, but  nothing there to suggest seismic  measurements  !!

thanx for those  links , I appreciate it.   
" got it !!  " .   haha aha ha aa

you'd think that since we already have an elaborate USGS network of seismic stations that stuff like this would be
surperfulious  , totally unnecessary.  after all, the USGS stations
are a result and evolution of  over a century of study and research
into measuring earthquakes.  don't they represent the " pinnacle  " of application of  lessons learned !   well, yes they do ..... but
there " might " be some other interesting ( to some people ) things going on down there  that the design of these stations ( conviently ) totally eliminates from  their measurement.

Well "launch the viewer" and have a play with this as well:-
