Coal, oil, gas fossil fuels are all contained in the earth's crust and make up an extremely small fraction of it. The crust is just 1% of the volume of the planet and the mantle that the rigid plates float on is 84% of the volume. I'd wager that all the crude fossil fuels in the world might be able to have a minor impact on a single decently sized volcano if it were all in one spot beneath it, but it's not. The views above are primarily opinion formed off the cuff combined with a few minutes of research. I'm open to being shown that I am incorrect.
