August 8, 2025 — View of Kīlauea South Flank

This aerial image, taken during a Kīlauea summit overflight on August 8, 2025, looks southwest towards the ocean. In the foreground, two small lava flows that were erupted from Kīlauea in 1982 and 1971 are visible. The darker one on the left is from September 1971, while the shiny grey one on the right is from September 1982. Behind that, the Koa’e fault system, a series of en echelon cracks or normal faults, can be seen running left to right. The dark brown tephra deposits from the ongoing eruption (far right) can be seen on the right side, covering a swath of the landscape downwind. In the distance, the haze you can see is volcanic air pollution (vog) from the degassing plume from the vents in Kīlauea caldera after episode thirty ceased. USGS photo by M. Decker
