After Jim, Carlos, and Dave worked with Nikhil and Michael to get Seismon up and running again (see LHO aLOG 43486), we've been confused by the estimate of the peak surface velocity on-site. 

See attached trends: I compare the 30 - 100 mHz RMS ground velocity of seismometers on site against the EQ magnitude and predicted peak velocity as reported by seismon. One can see that the peak velocity is consistently reported orders of magnitude larger than what's seen on site, and for earthquakes of magnitude ~5 -- where seismon predicts we should see a peak velocity in the ~5 um/sec range on site -- they're just not at all visible in the 30 -100 mHz band. 

Of course, I know that peak velocity is not the same and RMS in the 30-100 mHz frequency band. Thus my request to team Seismon: can we create a prediction for the 30-100 mHz RMS velocity on site in addition to the peak velocity estimate? This would greatly facilitate control room operation.
