As a result of these harmonic tremor signatures on January 25th, a team of USGS/University of Utah geophysicists went up to Yellowstone on January
27th, leaving from Salt Lake City, worked through that night taking down seismograph stations, to put them on-line the next morning, and then began
conducting seismic refraction studies, with these detonations witnessed in real time. I also know that on February 2, numerous terabytes of data were
secured on a dedicated University of Utah computer, and a closed-door meeting was held from Yellowstone that day.
Here is a helpful site to view all the daily Yellowstone Seismograms at once.

If you set the date to January 27, 2011, and update the thumbnail display, you can see that the University of Utah geologist team turned off the
seismographs all at around 22:27 MST..
If you then change the date to January 28th, and update the seismograms, you can see they powered the stations back up at about 05:36 MST. Some of the
stations are initially turned on, but not set to register (having flat seismic lines).
Then at 11:15 MST these few stations are set to register seismic waves as well, then shortly thereafter they began setting off a series of seismic
charges, shown by pronounced p-waves with no s-wave signatures. This is seen in the seismograms below
