Lava lake spattering at Halema‘uma‘u Crater

The lava lake in the Overlook crater, within Halema‘uma‘u Crater at Kīlauea's summit, undergoes frequent periods of spattering. The spattering is normally at the lake margins, and the surface crust often flows towards, and is consumed at, the spattering source. Large bubbles bursting at the surface drive the spattering activity, as shown occasionally by large spherical bursts.
