Western vent in Halema‘uma‘u crater - February 24, 2021
A telephoto image of the western fissure within Halema‘uma‘u crater, at the summit of Kīlauea Volcano. On Wednesday, February 24, 2021, the northern-most vent of the fissure was producing occasional weak bursts of spatter (center). This vent fed a new lava flow which was emplace between the spatter cone and the crater wall and advanced a short distance along the northwestern lava lake levee (right). This flow was weakly active when field geologists observed it on Wednesday afternoon. USGS photo taken by L. DeSmither.
