Halemaʻumaʻu crater southwest crater wall fountain - June 8, 2023

A telephoto view looking down on the fissure vent in the talus pile in the southwest corner of Halema‘uma‘u crater, taken from the western crater rim. Over the past 24 hours, this fissure vent has built up a spatter cone and spatter ramparts around its lava flow that cascades down to the crater floor. This flow is feeding lava into the southwestern part of the newly formed lava lake. USGS photo by D. Downs.
