We’ve touched on volcanoes and the fluid dynamics of lava a couple of times here at FYFD, but over at Wired volcanologist Erik Klemetti has some wonderful photos and videos he took while visiting an active lava flow in Hawaii along with great explanations of the flow shapes and processes. Above we see him using a rock hammer to remove a sample from an active flow. Klemetti describes the lava’s behavior as taffy-like – extremely viscous and stretchy but prone to break like a plastic. Be sure to check out his posts! (Photo credit: E. Klemetti; submitted by @FlexMonkey)
