September 8, 2022 — Mauna Loa Sulphur Cone MultiGas Station Maintenance
A Hawaiian Volcano Observatory scientist peers into the fissure that erupted in 1950 from the Southwest Rift Zone of Mauna Loa near Sulphur Cone. Water vapor and sulfur gases are still emitted from this fissure and surrounding area, which is at an elevation of 3,430 meters (11,240 feet) above sea level. The contrasting colors set against a backdrop of steam and fume make for a dramatic and beautiful scene. USGS image by T. Elias.
