Great video, but it needs something to give a sense of scale. How big is that river of lava? That forming cone?
You can still hear the participants swearing a little bit, but it's not as bad as that other site, where even the url had the f-word in it.
But anyway, this second video with the sightseers gives you a little better sense of the scale. It's looks big, but not a Mount Saint Helens.
