Summit lava lake in Halema‘uma‘u remains at high level

Detailed Description

Over the past week, the summit lava lake in the Overlook crater rose and spilled out onto the floor of Halema‘uma‘u Crater, creating the dark flows in the south part of Halema‘uma‘u (left side of crater from this direction). The extent of the lake itself, set within the Overlook crater, is slightly difficult to distinguish from this view but the spattering at the lake margin is visible. The overflows onto the Halema‘uma‘u Crater floor, not counting the area of the lake itself, total about 11 hectares (28 acres).
