Lava Lake Spattering at Halema'uma'u Crater

21 January 2014 Lava Lake Spattering at Halema'uma'u Crater The lava lake in the Overlook crater, within Halema'uma'u Crater at Kilauea'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.
