Video: Clear skies and sunshine provided a spectacular view of Kīlauea Volcano's summit lava lake this morning. Spattering on the north side and center of the lake surface—a departure from its more common location on the southeast side of the lake—occasionally happens when the surface flow direction reverses. Spattering occurs when gas bubbles within the lava lake burst.
