Hornito on Halema‘uma‘u crater floor—July 19, 2022

Telephoto aerial image of a hornito on the surface of the eastern part of Halema‘uma‘u crater floor at the summit of Kīlauea. In the foreground, Hawaiian Volcano Observatory monitoring equipment on the eastern rim of Halema‘uma‘u crater gives a sense of scale. Several hornitos, each several tens of feet tall, rise from the floor of Halema‘uma‘u crater. These hornitos are small spatter cones that are supplied with lava from beneath the solidified surface crust that forms the floor of Halema‘uma‘u crater. USGS image by J. Chang.
