According to a warning given by French and Italian researchers, Etna “is slowly transforming itself from an effusive volcano, which means one with a slow lava flow and low gas emission, into an explosive volcano. ”
Prantsuse ja Itaalia teadlased hoiatavad, et Etna kui „purskelise iseloomuga vulkaan, millele on omane aeglane laavavool ja vähene gaasieraldus, on aegamisi muutumas plahvatusliku iseloomuga vulkaaniks ”.
