Lava sloshing and spattering in west vent in Halema‘uma‘u crater at Kīlauea volcano
A telephoto view of the west vent along the western wall of Halema‘uma‘u crater at the summit of Kīlauea. On November 9, spatter bursts in the west vent cone triggered sloshing on the surface of the ponded lava. Spatter was thrown about 6–9 m (20–30 ft) above the pond surface and occasionally deposited onto the rim of the cone. USGS photo by J. Schmith.
