    Watching an obsidian lava flow: a glacier of hot volcanic glass

    Small eruptions of runny red basalt lava happen almost daily on Earth, at famous volcanoes such as Etna in Sicily and Kilauea on Hawai’i. We are all familiar with images of rivers of molten lava flowing down volcano flanks, both from news reports and the movies. Scientists have a good understanding of basalt lava flows as there have been ample opportunities to observe how they advance.
