Explosive activity at Mt. Etna

by Jonas Kuhn, Heidelberg University, Heidelberg, Germany

Lava fountaining at Mt. Etna's south east crater. The image is taken in the near infrared spectral region (~720nm-1000nm), which enhances the contrast of clouds and the volcanic plume to the background sky and highlights the lava's thermal emission.
