A powerful eruption column rises above Soufrière volcano on April 17, 1979. The height of the eruption column was estimated to be 19 km. The smooth-textured "skirt clouds" in the center of the photo were produced by condensation of subhorizontal layers of moist air that were carried up by the eruption column.
