During an overflight of fissure 8 this morning, HVO geologists observed low-level spattering on the new pad of lava within the cone. Slow-moving lava had just barely entered the spillway, but was not advancing down the channel. Video taken Monday, September 3, 2018 courtesy of U.S. Geological Survey

Seismicity remains low and ground deformation is negligible at the summit of KÄ«lauea Volcano. Earthquakes, probably aftershocks of the magnitude-6.9 earthquake in early May, continue on South Flank faults.
On the volcano’s lower East Rift Zone (LERZ), the crew on this morning’s overflight confirmed that weakly active lava continues to fill the deep crater in the fissure 8 cone with no lava extending outside the walls of the cone and no flows heading down the spillway. Other vents were steaming due to morning rains.
Sulfur dioxide emission rates at the summit, PuÊ»u ʻŌʻÅ, and LERZ are drastically reduced; the combined rate (
