September 3, 2025 — Kīlauea summit vents degassing with webcam

This view is from the south rim of the summit caldera on Kīlauea and shows the vent complex formed during the ongoing eruption. The vent area consists of overlapping lobes of spatter-fed flows, layers of tephra, and thin fluid lava flows. Much of the rubbly material in the central portion of the photo originates from "spatter-fed" flows, which forms as hot spatter from the lava fountains piles up around the vents, and then coalesces to form a very viscous type of secondary lava flow.
