September 14, 2023 — Active spattering at Kīlauea
A row of scones in Halema‘uma‘u are actively ejecting spatter, which helps build the height of each structure. Cone heights of 20 meters (66 feet) have been measured by field teams. Of the line of vents spanning 0.8 miles (1.4 km) that were observed active during the initial phases of the eruption, only six remain active as of September 14, 2023. USGS photo by L. Gallant.
