A screenshot from the video of the lava flow at Etna (image: Boris Behncke)A spectacular video of the oozing lava flow emanating from the eruptive fissure was captured by the INGV volcanologist Boris Behncke. How does lava sound when it comes to the surface of the Earth? Listen to a lava flow oozing out of its effusive vent high on the southwestern side of #Etna, 28 August 2025. That day no visits by tourists were allowed on the site, which permitted this (relatively) clean recording pic.twitter.com/iNT5ONQryy— Boris Behncke (@etnaboris) August 30, 2025
