The summit lava lake level remained high throughout the day, sending occasional overflows across the floor of Halema‘uma‘u Crater. In the upper left, a spatter site is pouring lava into a small overflow directed towards the north. In the bottom right, a passive overflow of the rim is sending a more sluggish overflow onto the floor. Just left of the center of the photo, a spatter site has constructed a spatter rampart on the lake margin.

On Kīlauea Volcano's summit, the Halema‘uma‘u lava lake's high standing lake level produced intermittent overflows onto the crater floor. Smaller overflows and spattering have started to build a few discontinuous levees and a spatter cone around the lake margin, shown in these video clips taken from the lakes north and northeastern margin.
