The ongoing eruption of Kilauea is interesting for a number of Metabunk related reasons.
Firstly there's the association of volcanos with the solar radiation management proposals in the field of geoengineering. Volcanoes spew a lot of sulphur dioxide and ash into the air which (simplifying) makes it hazy and reflects sunlight back into space. This most famously happened with Mount Pinatubo in 1991
Kilauea is a very different type of eruption — more like a big gas leak than a huge explosion, but it's still (like most active volcanos) a source of sulfur dioxide and a factor in the global climate. Studying how the increase in emissions affects things will tell us a little more about how we might use similar mechanisms for geoengineering — or how we might not want to use them if the side effects are worse than the cure. Drawing attention to the real science of geoengineering is a valuable way of reaching people who are convinced that the government is already secretly doing geoengineering with "chemtrails" being sprayed from planes.
An even more extreme conspiracy theory is that the eruption was triggered deliberately, perhaps with a supposed mega-weapon like HAARP (which is incapable of doing anything other than briefly exciting a tiny spot of the atmosphere on the edge of space above Alaska). The reasons given for doing this will likely be related to the "Agenda 21" conspiracy theory, which says the elite want to drive people from their land and force them to live in city apartments so the elite can have the countryside for safaris and suchlike. This (fringe) belief will be bolstered by the affected land being "homesteads" – a house with a few acres.
As that's such a nonsensical and scientifically implausible theory it's a bit tricky to address, especially with the mix of strongly felt libertarian politics. But perhaps the coverage of Kilauea will help a few people better understand the science behind eruptions, and how they are both inevitable and currently beyond the control of humanity.
Finally the images of red hot lava rolling over people's lawns and around trees might help a few people understand the problems with the theory that unburnt trees next to burnt-out houses is evidence that the houses were zapped with energy beams from space (again as part of agenda 21). Having a very hot thing a few feet from a tree does not automatically mean the tree bursts into flames.
For me and millions of school kids, volcanoes have always been associated with a fun and accessible side of science. Hopefully the net result of the current attention on Kilauea will be a rise in interesting in that science, and not a rise in interest in unfounded conspiracy theories.
