Kīlauea summit eruption in Halemaʻumaʻu crater - October 4, 2021

Detailed Description

A telephoto view of fountaining at the western vent in Halema‘uma‘u crater, at the summit of Kīlauea. Spatter from the fountain has built a horseshoe-shaped cone around the vent in the western crater wall. Molten spatter accumulating on the cone forms a tiny stream of lava down the north side (bottom center). This photo was taken on October 4, 2021, from the northwest caldera rim. USGS photo by M. Patrick.
