Thor Thordarson (London: Geological Society, 2009), p. 299</ref> It is often a few meters wide and may be many kilometers long. Fissure vents can cause large flood of lava and later lava tubes. After some time the eruption cools down gradually and builds up [[crater]]s.<ref>{{cite web |url=http://www.volcano.si.edu/learn_galleries.cfm?p=5 |title=Fissure Vents |author= |date= |website= |publisher=Smithsonian Institution |accessdate=28 March 2015 |archive-date=17 February 2015 |archive-url=https://web.archive.org/web/20150217083727/http://www.volcano.si.edu/learn_galleries.cfm?p=5 |url-status=dead }}</ref> == References == {{commons}} {{reflist}} {{sci-stub}} [[Category:Volcanic craters|*]]
