Yellowstone Harmonic Tremors Causing Uplift Under Yellowstone Lake
A review of the tremor swarms below Yellowstone Lake and the Lake Outflow data show a correlation between the periods of Harmonic Tremors and the volume of water flowing out of the lake.
This correlation could mean that ground deformation (raising) is taking place under Yellowstone Lake as a direct result of the earthquakes and harmonic tremors ongoing since December 26th.
***(All data devices waterflow and sesmic resumed data feeds late this afternoon, per note below they were offline for several hours)****
It is also interesting to note that the University of Utah and USGS started taking the web reports from many of many of the seismographs in Yellowstone off-line yesterday afternoon so the general public can no longer view them.
