[quote:Anonymous Coward 35060043:MV8xNzg2NDI0XzM2MzMxNjA0X0Q5M0JBNDUx] An excellent story of how and why during the eruptions of lava fountains formed http://www.wired.com/wiredscience/2013/02/etnas-explosive-last-three-days/#disqus_thread Boris Behncke 3 days ago ...these episodes are the result of the periodic foaming of magma in the conduit, even if not much new magma is furnished from depth. It's the gas that does the trick mostly. Gas is originally dissolved in the magma (like carbon dioxide in a bottle of sparkling water, as long as it's under pressure you don't see it because it is actually *part* of the water), and as the magma rises, the gas decompresses and separates from the molten rock, forming bubbles. These bubbles tend to rise faster than the surrounding magma and accumulate in the upper part of the magma column, which is capped by more viscous, cooler or even solid magma, so much of the gas don't escape. Instead, the bubbles become more and more and coalesce, requiring more and more space, and the result is that a sort of magma "foam" forms, which then rapidly expands, letting the gas and a minor fraction of magma escape. And that's what makes a lava fountain. The magma foam comes out as scoriae (or, in more silica-rich, highly explosive eruptions, as pumice), but its proportion relative to the gas escaping simultaneously is vanishingly small. So if you think of those impressive fountains of liquid lava and towering columns of dark ash, consider what immense quantities of gas (foremost, water vapor, and then also some good quantities of carbon dioxide and sulfur dioxide) are released in such events!
