Explanation: Sometimes both heaven and Earth erupt. In Iceland (http://www.cia.gov/cia/publications/factbook/geos/ic.html) in 1991, the volcano Hekla (http://en.wikipedia.org/wiki/Hekla) erupted at the same time that auroras (http://www.exploratorium.edu/learning_studio/auroras/) were visible (http://www.iww.is/art/shs/) overhead. Hekla (http://volcano.und.nodak.edu/vwdocs/volc_images/europe_west_asia/hekla.html), one of the most famous volcanoes (http://www.crystalinks.com/volcanoesactive.html) in the world, has erupted (http://www.volcanolive.com/faq.html) at least 20 times over the past millennium, sometimes causing great destruction (http://www.decadevolcano.net/santorini/santorini_introduction.htm). The last eruption (http://hraun.vedur.is/ja/englishweb/heklanews.html) occurred only six years ago but caused only minor damage. The green auroral band (http://antwrp.gsfc.nasa.gov/apod/ap010402.html) occurred fortuitously (http://www.nationalgeographic.com/ngm/100best/wallpaper09.html) about 100 kilometers above the erupting lava (http://volcano.und.nodak.edu/vwdocs/frequent_questions/group1_new.html). Is Earth (http://volcano.und.nodak.edu/vw.html) the Solar System's only planet with both auroras (http://www.physicsweb.org/article/news/5/1/10) and volcanos (http://solarsystem.nasa.gov/news/display.cfm?News_ID=12955)?
