A Hawaiian Volcano Observatory gas scientist works to install a newly calibrated Multi-Gas instrument at the Sulfur Cone site. At an elevation of 3,430 meters (11,240 feet) above sea level, the air is rare! Working conditions are far more strenuous for HVO field teams at these high elevations due to the much lower levels of oxygen in the air to breathe.

During an overflight at approximately 8:15 a.m. HST on June 6, 2024, USGS Hawaiian Volcano Observatory scientists observed the extensive crack features on either side of the now inactive fissures from the June 3 Kīlauea Southwest Rift Zone eruption. Cracks range in length and are parallel to the fissure system. USGS photo by A.R. Nalesnik.

Continuous water-quality data are collected in streams like War Branch (pictured) using sondes, which are mounted to submerged in-stream structures like the one pictured here. These structures are constructed out of metal u-channel posts, and the data cables which connect to the sondes are protected by PVC pipes.
