Anyway, this shall serve as our educational thread. For interesting facts that you know, or are looking up, etc. (Not the same as the 'What have you learned today' thread...that's for stuff you 'accidentally' learn, after all... ) Just stuff you think's neat. Got the idea from the combination of myself posting scientific information in the random thread, and hearing Cliff spout off with some of his 'facts' on TV.
The source linked directly below this quote wrote:New research suggests that how often Old Faithful and other Yellowstone geysers erupt may depend on annual rainfall patterns. USGS scientist Shaul Hurwitz along with colleagues at Stanford and Yellowstone National Park have discovered that changes of water supply to a geyser's underground plumbing may have a large influence on eruption intervals; that is, the time between eruptions. For example, geysers appear to lengthen and shorten their intervals on cycles that mimic annual dry and wet periods. The study results were published in the article, Climate-induced variations of geyser periodicity in Yellowstone National Park, USA, in the June issue of the journal Geology.
This is one of those things that stemmed from looking up things volcanic (as I do from time to time; volcanology fascinates me, especially the supervolcano [like Yellowstone or Lake Toba]). I ended up this time at the Yellowstone Volcano Observatory site, and that was on there.
