October 16, 2021 — ongoing Kīlauea summit eruption

The active west vent of Halema‘uma‘u as seen from the northwest rim. The lava at the vent exits from a narrow spillway and feeds into the lake. The radial pattern seen at the mouth of the spillway is created as the lava on the surface cools and is pushed away from the vent, forming a rope-like texture. USGS photo by E.
