Re: Harmonic Tremor

Yellowstone is active with geothermal activity of course, but if you were to see some harmonic tremors, then you probably have some magma moving around down there. Then the question is where might it be going? Given Yellowstone's history:

It's interesting to follow, like several years ago the ground was moving upward a little more than normal. The odds of anything significant happening in our lifetimes is very low of course, but one day it will happen and given Yellowstone's large size, it's something that could significantly impact a vast area of our country.
