Volcano and Aurora in Iceland
Explanation: Sometimes both heaven and Earth erupt. In Iceland in 1991, the volcano Hekla erupted at the same time that auroras were visible overhead. Hekla , one of the most famous volcanoes in the world, has erupted at least 20 times over the past millennium, sometimes causing great destruction . The last eruption occurred only two years ago but caused only minor damage. The green auroral band occurred fortuitously about 100 kilometers above the erupting lava . Is Earth the Solar System's only planet with both auroras and volcanos ?
