A telephoto view of the west vent in Halema'uma'u crater

A telephoto view of the west vent taken during this morning’s overflight of Kīlauea Volcano’s summit, at about 10:00 a.m. HST. The west vent in Halema‘uma‘u crater remains active, with two vents visibly glowing on either side of the spatter cone. The crusted over channel feeds lava into the lake from the western-most vent (left). USGS photo by L. DeSmither.
