That arcing of the lava really is something to behold. The pressures to push molten rock like that are impressive.

- asdfman123 10mo agoIt's just the weight of literally everything on the planet pushing down, as well as miles of rock :)
- louthy 10mo ago“just” is doing a lot of heavy lifting there ;)
- lisper 10mo agoLiterally! :-)
- praptak 10mo agoIndirectly. The actual spike of pressure that ejects the magma comes from the gasses dissolved therein. When the magma moves up, the pressure drops and the gasses become oversaturated and thus prone to violent release.
- asdfman123 10mo agoThe gas bubbles result form when pressure is reduced, like you mention. So there's actually less pressure near the surface, it's just more erratically applied. The pressure of the earth's subsurface is proving the animating force.
- wanderingstan 10mo agoIndeed. I just wish we could get a better sense of the scale, which is always hard in nature shots devoid of trees or human structures. A productive use of AI would be to place some houses and automobiles in the video for scale.
