Because harmonic tremors ARE an indication of moving magma. Moving magma, especially under pressure, is not a good thing. Is the magma moving and filling cracks and casuing more cracks in its upward movment toward the surface? Or, is something less ominous happening? That’s why I wanted to know about where the supposed information regarding harmonic tremors. came from... From blogs, posts or opinions, or from something more credible like USGS? Make a bit of difference.
Thanks. Doesn’t sound good. I wonder what the odds are that this thing is getting itchy and might need to scratch pretty soon?
It should be noted that all the earthquakes have been intense and concentrated in one area, which happens to be above the magna chamber. The scariest part of this story is the “harmonic tremors” that scientists have picked up. They are a low level constant rumbling, which usually indicates magna movement.

It has been reported and noted by the USGS that an earthquake swarm has been occuring under Lake Yellowstone since December 26th.
The attached webicorder display shows that after the tremor swarm activtiy died down this evening a new pattern of potential classic harmonic tremors has started and continues at the time of this posting. Harmonic tremors could mean lava is now moving under the Yellowstone super volcano.
The USGS has made no updates since these tremors began.
