North of Iceland’s Fagradalsfjall, a new volcanic fissure opened in July 2023. This drone footage from Isak Finnbogason captures that fissure on its first night. Lava fountains jet from the earth, forming a complex, slow-moving river. The similarities between flowing lava and more common liquids like water never ceases to fascinate me. Even with the vast differences in temperature and viscosity, so much of their physics remains recognizably the same. (Image and video credit: I. Finnbogason; via Colossal)
