According to USGS, the Caldera is currently condition green, just below the Cascade range condition green. Not much concern over that.

I suppose there might be some science linking solar activity or gravitational shifts affecting seismology. In some remote way, I suppose warping the magnetic field could put some stress on something somewhere, or some object sailing by might add some gravitational stress somehow. But the scale of the effects would be so miniscule, I would have think it'd be akin to me jumping up and down in one spot (I am a pretty big feller). What do you suppose the odds are I could jump up and down beside old faithful and cause the whole thing to fall in? LOL
