...some of the links above contain very interesting
information , especially when compared against the USGS station
equipment.  the chart result of traces is quite different from USGS
and the equipment differences explain why.  also, maps of sensor
placement  ( usgs and the others )  are interesting to ponder as well...

One of the pages mentions that the sensors around Corn Creek
are funded by the DOE and also serve some kind of Antelope
Habitat study.

Looking at the placement of sensors, there are installations
at Warm Springs, TTR and several other locations surrounding
the ranges. It also seems that there are a comparitively large
number of faults around the ranges. It would make sense for
the DOE to study what the earth is doing before storing
nuclear waste or blowing up a big can of oil.

well ......... if that's the case , it's nice of them to finally think
of this stuff ...... decades after the horse is out of the barn 
isn't it  !   ha ha hahahah ahaah    

still doncha think that ,  if purely quake related , that USGS
equipment is totally adequate  for that application ?  it easily
identifies all  those mag1 surface sonic booms - explosions
on a daily basis , doesn't it ?  that , and why does this equipment
display quake - shake data in frequency ranges unimportant to 
USGS ?     why indeed ?   

herze some interesting data / event  as seen  on those 
" so called " REV earthquake sites .....

look on the day of  2007-06-27 through 2007-06-28

first look at the chart for the event that starts on the 2 to 4 a.m.
line , starts a little about 3 a.m. but gets heavy about  3:30
can continues past 4 a.m. somewhat 

first look at over on the west coast in California

http://rev.seis.sc.edu/stations/TA/T06C?year=2007&month=6&day=27&hour=20&station_dbid=1349&channel_dbid=2616

then look at what it looks like , around here,  in Alamo , Nv
http://rev.seis.sc.edu/stations/TA/T11A?year=2007&month=6&day=27&hour=20&station_dbid=1586&channel_dbid=3508

then what it looks east at Idaho Springs , Colo ......
http://rev.seis.sc.edu/stations/US/ISCO?year=2007&month=6&day=27&hour=20&station_dbid=1661&channel_dbid=3831

this event starts right after 3 a.m. at all 3 locations .......

it's strongest ( at the start ) on the west coast with major activity 
that lasts over 30 minutes , and starts to get REAL active about
3:30 in California and Nv.  
 
it's less strong in Nv but the waves show that it's slightly later
than the  California suggesting it's traveling east or radiating out
....

it gets to Colo  15 min  later but picks up amplitude as compared to
the Nv chart  ( that's a VERY slow  migration of that event compared
to a  normal earthquake ) 

now THATS interesting stuff ............

notice that for the same time period , the USGS shows pretty much
nothing happening in the same time period ......
http://quake.usgs.gov/recenteqs/Maps/117-37_eqs.htm
http://quake.usgs.gov/recenteqs/Maps/120-37_eqs.htm

let alone a large 30 minute event ........   this clearly illustrates
the dramatic differences  between the USGS and REV measuring 
equipment  and  range parameters measured. 

for all of us that have been looking to USGS for info .... makes you
wonder what else we have missed eh ??
( exactly why I have my own equipment and systems.  I've known for
years that USGS data is  missing a LOT of important  stuff , plus I
want more than they provide < infrasonics , nuke, IR etc > ).
